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 50:1 or higher
The output mode is flexible, which can either automatically upload data through communication interface ,or a linear analog voltage can be output through the analog interface.
LED displays instantaneous flow rate and cumulative flow rate, allowing field button configuration of flow meter parameters.
It can record the maximum and minimum values of instantaneous flow since power on, and it has the function of over range
RS485 communication module is provided to facilitate centralized control and remote transmission.
The same air connection as the traditional rotor flow meter
Mechanical size and flow range can be customized according to customer needs
Mechanical dimensions
Remark:Please contact the manufacturer for mechanical dimensions of other flow ranges.
