What is a negative pressure gas flow meter?

Project Overview

Negative pressure flowmeter is an instrument that measures flow. It can calculate the flow rate and flow rate by measuring the pressure drop of the fluid in the pipeline. The negative pressure flow meter consists of a sensor and a transmitter. The sensor is responsible for measuring the pressure drop in the pipeline, and the transmitter converts the measurement results into a standard signal output.

Negative pressure flow meters have many advantages, such as high measurement accuracy, good stability, high reliability, and easy operation. In addition, there are many types of negative pressure flowmeters, such as orifice flowmeters, venturi flowmeters, etc. The appropriate type can be selected according to different application scenarios.

When using a negative pressure flow meter, you need to pay attention to the following points:

1. Ensure the cleanliness in the pipeline to avoid impurities and dirt from affecting the measurement results.

2. When installing a negative pressure flow meter, ensure that the pressure in the pipeline is stable to avoid the impact of sudden pressure changes on the measurement results.

3. During use, regularly check whether the zero point of the negative pressure flow meter drifts to ensure the accuracy of the measurement results.

4. When selecting a negative pressure flowmeter, the appropriate type and specification should be selected according to the actual application scenario to ensure the accuracy and reliability of the measurement results.
