temperature), and the meter adopts method of constant differential temperature, therefore the meter do
not need to do temperature and pressure compensation in principle.
3.2 Specifications
Features

Measuring the mass flow or volume flow of gas

Do not need to do temperature and pressure compensation in principle with accurate measurement
and easy operation.

Wide range: 0.5Nm/s
～
100Nm/s for gas. The meter also can be used for gas leak detection

Good vibration resistance and long service life. No moving parts and pressure sensor in transducer,
no vibration influence on the measurement accuracy.

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)

Digital design, high accuracy and stability

Configuring with RS485 or HART interface to realize factory automation and integration
