Product Description

   Thermal gas mass flow meter is designed on the basis of thermal dispersion, and adopts method of constant differential temperature to measuring gas flow. It has advantages of small size, easy installation, high reliability and high accuracy, etc.

Product Overview

Features

l Measuring the mass flow or volume flow of gas

l Do not need to do temperature and pressure compensation in principle with accurate measurement and easy operation.

l Wide range: 0.5Nm/s~100Nm/s for gas. The meter also can be used for gas leak detection

l Good vibration resistance and long service life. No moving parts and pressure sensor in transducer, no vibration influence on the measurement accuracy.

l Easy installation and maintenance. If the conditions on site are permissible, the meter can achieve a hot-tapped installation and maintenance. (Special order of custom-made)

l Digital design, high accuracy and stability

l Configuring with RS485 or HART interface to realize factory automation and integration
