PSR series German Kobold flow switch

The measurement of liquid flow rate is based on various physical foundations. On the one hand, the flow rate of liquid or gas can be determined by the flow rate

Sensors directly measure. On the other hand, it can be monitored by measuring sensors. According to the application scope, medium type, and liquid temperature

Different flow meters or flow monitors can be selected for measurement. Kebao offers a wide range of high-quality flow meters, from simple baffle opening

When it comes to high-precision Coriolis mass flow meters, there are various types of applications. Flow monitoring of viscous media (such as petroleum)

Measurement can use various flow meters with different measurement principles, such as elliptical wheel flow meters, gear flow meters, and rotor flow meters. They

Long lifespan and high efficiency. With the development of ultrasonic flow meters, magnetic induction flow meters, and vortex flow meters, there is a growing demand for non moving measuring equipment

The demand is constantly increasing. Flow meters are used to measure flow rate in many industrial sectors, especially in the field of automated production. each

A flow sensor allows for rapid and automatic action for precise flow control. Triggered when the traffic reaches a certain level

The pure reaction system of the reaction is different from those systems that are specifically used as flow sensors for flow monitoring and accumulation.

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

Methods for evaluating performance, etc; Basic standards: the basic parameters, models, names, and 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 proper installation and use. There are some standards that only require correct installation and usage techniques, which are the product application properties in product standards.

The working principle of KOBOLD flowmeter is to use the vibration generated by the unbalanced pressure difference caused by the flow of fluid in a specific pipeline

A new type of flowmeter for measurement. KOBOLD flowmeter features: high precision, high range ratio, and extremely low pressure loss. No measurement part available

The moving parts have a simple structure and are easy to clean and maintain. After cleaning, there is no need to recalibrate.

Classification of flow sensors:

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

5) Classified by output signal: analog sensor, digital sensor

Functional characteristics of German KOBOLD flow sensor

1. 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 head loss of the water system,

However, due to the long-term impact of water flow on the baffle type, there is still a problem of fatigue, and even when calibrating the flow value, the set point drift may occur.

2. Usually used in places where accurate flow values are not required for protection, such as for sudden interruption of water flow in pipes. Targeting water sources domestically

There are very few designs for heat pump units.

3. 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,

The water resistance of each type of baffle does not exceed 0.5 meters of water column, which is greatly reduced compared to the target type water resistance.

4. Each baffle type flow sensor is equipped with the same fittings as the water pipe of the water ring heat pump unit, and only needs to be connected to the water pipe on site, without the need for baffles

Make any changes, and 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.

5. Based on feedback from the use of water ring/ground source heat pump units, the differential pressure switch can determine issues with the water pipeline installed on-site in the water ring heat pump unit,

It can avoid the situation where the heat exchanger freezes due to low water flow, and the flow sensor can also protect the heat exchanger when the water flow decreases due to clogged water filters

The situation where the heater is frozen and damaged, and there is no risk of fatigue damage to the target flow switch in the water pipeline pressure differential switch.

6. 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 many years

The feedback used did not find any malfunction in the differential pressure switch itself.
