LUGB2312C-P25Z Vortex Flow Meter

The LUGB2312C intelligent vortex flowmeter is a primary instrument used to measure the flow of liquid, gas, and steam in pipelines. It is a new type of intelligent flow meter based on the principle of Karman vortex street, with on-site LCD display function and variable output current signal or frequency signal for recording, adjustment, and control. Widely applicable to the measurement and control of superheated steam, saturated steam, compressed air, general gases (oxygen, nitrogen, hydrogen, natural gas, coal gas, etc.), water, and liquids (such as water, gasoline, alcohol, benzene, etc.) in industries such as petroleum, chemical, metallurgical, thermal, textile, paper, etc

Main characteristics of vortex flowmeter

No mechanical movable parts, not easily corroded, stable and reliable, long service life, long-term operation without special maintenance.

Using 16 bit computer chips, it has high integration, small size, good performance, and strong overall functionality.

According to the requirements of different users, there are various converters (electronic meter heads) available in high, medium, and low configurations.

According to user requirements, dual detection technology can be used to effectively improve the detection signal strength and suppress interference caused by pipeline vibration.

You can choose a converter (electronic meter head) with domestic intelligent seismic technology, which effectively suppresses the interference caused by vibration and pressure fluctuations.

Optional dot matrix display screen with Chinese and English menus, displaying multiple digits. The reading is intuitive and convenient, and can directly display multiple parameters.

The converter (electronic meter head) can output frequency, pulse, equivalent, three wire 4-20mA and two wire 4-20mA, analog signal, RS485 interface, Hart protocol output, etc.

Adopting EEPROM technology, parameter settings are convenient and can be saved.

And it can store historical data for up to one year.

Vortex flow meters are sensitive to flow velocity distribution distortion, rotational flow, and flow pulsation in pipelines. Therefore, the installation conditions of pipelines on site should be fully taken into account, and the requirements of the manufacturer's instructions should be followed.

1. Vortex flowmeter can be installed indoors or outdoors. If installed in underground wells, there is a possibility of flooding, and submersible sensors should be selected. Sensors can be installed horizontally, vertically, or obliquely on pipelines, but when measuring liquids and gases, attention should be paid to the installation position to prevent interference from bubbles and droplets,

2. The vortex flowmeter must have the necessary length of the upstream and downstream straight pipe sections. There are differences in data among various sources, which may be due to the fact that the vortex generator has not been standardized, and the impact of differences in shape and size remains to be verified; The experimental research on the necessary length of straight pipe sections for various types of flow blocking components is still insufficient, that is, it is not yet mature. Compared with throttling differential pressure flow meters, this work is still in its initial stage.

3. Connection between sensors and pipelines. Pay attention to the following issues when connecting with pipelines.

a、 The inner diameter D of the upstream and downstream piping is the same as the inner diameter D 'of the sensor, and the difference satisfies the following condition: 0.95D ≤ D' ≤ 1.1D.

b、 The piping should be concentric with the sensor, and the coaxiality should not be less than 0.05D '

c、 The sealing gasket cannot protrude into the pipeline, and its inner diameter can be 1-2mm larger than the inner diameter of the sensor
