How to Realize Accurate Measurement of Electronic Gas Volume Corrector

Date: 2022-Jan-29

MicroSensor Pressure Measurment

The gas volume corrector usually measures the temperature and pressure at the air inlet of the flowmeter. Since it is used for metering and charging and is mostly battery-powered, high accuracy, high-stability, and low-power consumption pressure sensors and temperature sensors are selected to ensure accurate measurement and longtime lasting operation.

According to the above requirement, Micro Sensor offers the following products for pressure and temperature measurement in gas volume correctors.

Pressure Measurement

Micro Sensor pressure sensors have a range of 0~1000 bar, and the power consumption is 5uA in standby mode. There are multiple pressure ports optional to meet different products integration requirements for different scenarios:

• MPM380 is a pressure sensor with housing and cable, the output signal is mV. 

• MPM3801 is a pressure sensor with a standard size; the output signal is IIC.

MPM3801A Digital Pressure Transmitter is a pressure sensor with different pressure connections, the output is IIC.

Temperature Measurement

For temperature monitoring requirements, Micro Sensor WZP temperature sensor and MTM integrated temperature transmitter are widely used for temperature monitoring in gas volume correctors. The temperature ranges are -200~500℃ and multiple pressure ports are optional. The WZ type temperature sensor uses PT1000 with pressure port, MTM integrated temperature transmitter has optional output signals of 4-20mA, RS485, and HART (IIC output is under development), and a variety of structures are custom designed available.
