Thermal mass meter

 

Ensure the accurate of measuring,stable performance,multi-flow unit switching,multi-function setting.

 

Thermal mass meter

With DC4-20mA four-wire output,which is more convenient for remote reception. Support MODBUS RTU RS485 protocol,coordinating the receiving system to collect more data and modify system

Thermal mass meter

Thermal gas mass flow meter is mainly used for measuring gas with low flow and the range ratio could reach 1:1000, which is better than gas flow meter on market and low flow could be measured.

Thermal mass meter

 Can be divided into five sections for correcting, this operation will make measuring more precision.

Installation location and straight pipe requirements

1. When installing the thermal mass flow meter, keep away from elbows, obstacles, reducers and valves to ensure a stable flow field. It is required to have a long upper straight pipe. The front straight pipe length is greater than 10D, and the rear straight pipe length is greater than 5D.

2. When user site cannot meet the requirements of the straight pipe section, the gas rectifier could be connected in series to greatly reduce the requirements for the straight pipe section.
