Product features
With high sensitivity, the measurement range can be as low as 0.01Nm/ SEC and as high as 65Nm/ SEC through the independent integrated module.
Using the principle of thermal mass flowmeter, the sensor can directly measure the fluid mass.
Unique MEMS design makes for greater stability and durability.
Standard power supply voltage is 8~24VDC.
Industrial standard communication interface can easily realize network and remote control.
