Product features
The sensor chip adopts heat mass flow measurement without compensation of temperature and pressure, which ensures the high-precision measurement of the flowmeter;
Multiple sensor integration is implemented on a single chip with a range ratio of 100:1 or higher;
LED displays instantaneous flow rate and cumulative flow rate;
It has gas recognition function;
Ultra-low power consumption, internal lithium battery power supply can work for a long time;
The output mode is flexible, RS485 communication module, 4-20mA current and 0-5V voltage output module are optional.
