Product features
Using microelectromechanical system chip processing technology and mass integrated circuit production technology and material growth technology, the size of sensor hu has been reduced to micron level, which greatly improves the sensitivity of the flowmeter.
Multi-sensor integration is implemented on a single chip, which greatly improves the range ratio of the flowmeter.
The zero point stability of the sensor is greatly improved compared with the traditional thermal mass flowmeter.
Combined with the microcomputer intelligent technology of secondary instrument, the flowmeter has good repeatability, and the measurement is accurate and reliable.
Technological advances have simplified the structure that has greatly reduced pressure loss and greatly reduced energy consumption compared with traditional mechanical instruments.
Using LCD to display instantaneous flow rate and accumulated flow rate, clear and intuitive, easy to see the data.
The product integrates electromagnetic compatibility design technology and has higher anti-interference ability.
The flowmeter is equipped with RS485 communication module, which can realize centralized management with the upper computer network.
Optional 4-20ma standard current signal output and pulse output.
