Overview
Enviro Forest thermal mass flow meters are mainly used for measuring gas with low flow and the range ratio could reach 1:1000, which is better than gas flow meters on the market and low flow could be measured. It can provide high accuracy, Stable performance, Multiple flow units seamless switching and multi-function setting. With DC 4 mA to 20 mA four wire output,which is more convenient for remote reception. Support MODBUS RTU RS 485 protocol, coordinating the receiving system to collect more data and modify the system.
Features
- LCD HD display
- Dual power supply
- Refined shielded rod
- Anti shading design
- High precision reinforced sensor
- Could measure mixed gas
- Wide flow range
- High sensitivity
