An air flow sensor is a sensor that measures the amount of air drawn into the engine. In order to obtain the optimal concentration of the mixture under various operating conditions, the electronic control gasoline injection engine flow sensor must accurately measure the amount of air inhaled into the engine at each moment, which serves as the main basis for ECU calculation (control) of fuel injection quantity. If the air flow sensor or circuit malfunctions and the ECU cannot receive the correct intake signal, it will not be able to control the fuel injection amount normally, which will cause the mixture to be too rich or too lean, resulting in abnormal engine operation.

Folding Editor: Introduction to this paragraph

The verification regulations and standards for flow meters are the guarantee for accurate measurement of flow sensors. Accurate measurement of traffic is crucial in many fields and is widely used in the economic sector, such as environmental monitoring, healthcare, safety protection, and trade settlement.

Folding edit: Style classification in this paragraph

According to the structural types of flow sensors, they can be divided into several types such as blade (wing plate) type, measuring core type, hot wire type, hot film type, Karman vortex type, etc.

According to their standard properties, they can be classified into the following categories. Method standards: Calculation methods, detection methods, testing methods, and performance evaluation methods for some sensors, etc; Basic standards: the basic parameters, models, names, and professional terminology used in the measurement process for some sensor specifications; Product standard: This type of sensor has been included in Kuaiyiyou, which specifies the technical requirements, acceptance rules, testing methods, and product classification of the sensor. In addition, there are also requirements for correct installation and use. There are some standards that only require correct installation and usage techniques, which are the product application properties in product standards.

If classified according to Chinese standards, it can be divided into four categories: enterprise standards, local standards, industry standards, and national standards.

1) Classified by input quantity: displacement sensor, velocity sensor, temperature sensor, pressure sensor, etc

2) Classified by working principle: strain gauge, capacitive, inductive, piezoelectric, thermoelectric, etc

3) Classified by physical phenomena: structural sensors, characteristic sensors

4) Classified by energy relationship: energy conversion sensors, energy control sensors

Folding and editing features of this section

At present, baffles can be designed according to the size of the water flow rate to reduce the water resistance generated by the flow sensor and minimize the pressure head loss of the water system. However, due to the long-term impact of water flow on the baffle type, fatigue problems still exist, and even if the flow rate value is calibrated in the factory, set point drift may occur.

Usually used in places where precise flow protection is not required, such as for sudden interruption of water flow in pipes. There are very few designs for water source heat pump units in China.

The baffle type is specifically developed for water flow monitoring of water ring/ground source heat pump air conditioning units. It is equipped with different baffles for different pipe diameters, and the water resistance of each baffle does not exceed 0.5 meters of water column, which is greatly reduced compared to the target type water resistance.

Each baffle type flow sensor is equipped with the same fittings as the water pipe of the water ring heat pump unit. On site, only the water pipe needs to be connected without making any changes to the baffle. In addition, the pressure of the baffle type water flow switch is greater than 25 bar, making it a low-cost water flow switch for water ring heat pump units with low water flow requirements.

Based on feedback from the use of water ring/ground source heat pump units, the differential pressure switch can effectively identify problems with the water pipeline installed on site, avoiding situations where the heat exchanger freezes due to low water flow. The flow sensor can also protect the heat exchanger from freezing due to a decrease in water flow caused by clogged water filters. Additionally, there is no risk of fatigue damage to the target flow switch in the water pipeline differential pressure switch.

Especially when there is a small amount of air in the water pipeline, the flow sensor works very stably and does not float like a target flow switch. After years of use, feedback has not found any faults in the pressure differential switch itself.

Folding edit: Temperature installation method in this section

1. One time metering system: This installation situation refers to the situation where there is only one metering system in the entire heating system.

2. Secondary metering system: Unlike the primary system, the metering at the installation location belongs to the secondary metering.

3. Individual heating metering for household users: With the popularization of household metering and the promotion of heating energy-saving projects, this installation method is currently quite common.

4. Distribution metering for vertical heating: mainly used for heating metering in vertical heating systems.

Folding editing principle of this paragraph

Basic principles of folding

The basic principle and type of ultrasonic flowmeter: When ultrasonic waves propagate in a flowing fluid, they carry information about the fluid velocity. Therefore, by receiving ultrasonic waves, the flow velocity of the fluid can be detected and converted into flow rate.

According to the detection method, ultrasonic flow meters can be divided into different types such as propagation velocity difference method, Doppler method, beam offset method, noise method, and correlation method. Acoustic flowmeter is a non-contact instrument that has only been applied in the past decade with the rapid development of integrated circuit technology. It is suitable for measuring fluids that are difficult to contact and observe, as well as large pipe flow rates. It can be linked with a water level gauge to measure the flow of open water. The use of ultrasonic flow does not change the flow state of the fluid and does not generate additional resistance, as it does not require the installation of measuring elements in the fluid. The installation and maintenance of the instrument do not affect the operation of the production pipeline, making it an ideal energy-saving flowmeter.

Industrial flow measurement commonly faces the problem of difficulty in measuring large pipe diameters and large flow rates. This is because general flow meters face manufacturing and transportation difficulties as the measuring pipe diameter increases, resulting in increased cost, energy loss, and installation. Ultrasonic flow meters can avoid these disadvantages. Because various types of ultrasonic flow meters can be installed outside the pipeline for non-contact flow measurement, the cost of the instrument is basically independent of the size of the measured pipeline diameter. However, the cost of other types of flow meters increases significantly with the increase of diameter. Therefore, the larger the diameter, the more cost-effective the ultrasonic flow meter is compared to other types of flow meters with the same function. Considered a good instrument for measuring large pipe diameter flow, the Doppler method ultrasonic flowmeter can measure the flow of two-phase media, making it suitable for measuring dirty and dirty flows such as sewers and sewage. In the power plant.

Folding fluid characteristics

Fluid types include liquid, gas, and vapor. Some sensors (such as electromagnetic sensors) cannot measure gases; Inserting a thermal sensor cannot measure liquids.

Temperature, pressure, and density are important parameters for selecting sensors, especially under operating conditions. For gas flow, it is also necessary to understand whether its volumetric flow rate is in working condition or standard condition.

The significant difference in viscosity of viscous liquids can affect their selection. For example, for liquids with high viscosity, volumetric flow sensors should be used instead of flow sensors such as turbines, floats, and vortex streets.

For fluids with corrosion, scaling, and dirt, sensors with rotating and detecting components should not be used. Even for ultrasonic and electromagnetic flow sensors, errors can still occur due to corrosion of pipelines. If the diameter is 50MM and the scale is 0.5-1mm, it will result in an error of 0.5-1%.

Special parameters and certain fluid parameters can affect the operation of sensors, such as compressibility coefficient affecting differential pressure equations; The specific heat and thermal conductivity affect the heat equation; Conductivity affects electromagnetics; The speed of sound affects ultrasound.

Single phase and multi-phase refer to substances with the same physical and chemical properties in a system, with distinct interfaces between different phases. In industry, single-phase flow is commonly used, but with the development of industry, flow measurement problems such as multiphase flow (gas-solid, gas-liquid, liquid-solid, or gas-solid) have emerged.

Folding and flowing state

Unlike many physical parameters such as pressure, temperature, level, and composition, flow rate must be based on fluid flow as there is no flow without it.

Both full and non full pipes should generally be filled with fluid, but when the liquid flow rate is small and the pipe is horizontal, non full pipe flow may occur. Non full pipe flow sensors are already available.

Folding technology parameters

Total volume and flow volume (measured in M3 or KG), commonly used for trade accounting, with high accuracy. Flow rate (instantaneous units are M3/H, KG/H), commonly used in process industries, is the source of information for control systems.

Continuous, the output of flow sensors is generally continuous, while switch values can be used for simple binary control or equipment protection, requiring good reliability.

Accuracy depends not only on the sensor itself, but also on the calibration system, which is an external characteristic. To indicate the accuracy within what flow range, and if used for control systems, it should also be considered to match the accuracy of the entire system. Attention: The error indicated by the manufacturer is% FS (upper limit); Still% RD (measured value).

Repeatability refers to the consistency of multiple measurements of a certain flow rate value under constant environmental conditions and medium parameters, which is a characteristic of the sensor itself. In process industry control systems, repeatability is often more important than accuracy. Many manufacturers mislead repeatability as accuracy, which should include repeatability and flow uncertainty of calibration devices.

The ratio of maximum to minimum flow rate within a certain accuracy range. Differential pressure flow sensors can have a large range ratio from the sensor itself, but are limited by secondary gauges and generally only have a 3:1 ratio.

Pressure loss flow sensors (excluding electromagnetic and ultrasonic sensors) all have detection components (such as orifice plates, turbines, etc.), as well as forced changes in flow direction (such as elbows, Coriolis sensors), which will result in irreversible pressure loss. It will increase the power of transmission to maintain normal operation, and some of them are large in amount. In today's era of promoting energy conservation, they should be taken seriously.

The output signal is generally a standard analog signal (0~10V, 4~20MA, etc.), which cannot meet the requirements of system development. Communication requires digital signals. ROSEMENT has introduced the HART protocol and RS232/RS485 converter, with RS232 limited to 2KM and RS485 capable of up to 10KM.

The response time of the output signal with changes in flow parameters is as short as possible for the control system; For pulsating flow, a slower output response is desired.

The performance indicators of comprehensive performance sensors are interdependent, such as a pressure upper limit of 2MPA in the sample; If the temperature is 250 ℃ and the diameter is 1M, then when the diameter is 1M, the pressure may only be 1.5MPA and the temperature can only be 200 ℃, which cannot be both extreme values.
