Flow range
Setting friendly – Users can enter the sensor setting via button or Comate app
- Read & Set on Screen
PTF520 has integral TFT 2” High Resolution display with two capacitive key for setting
- Read & Set on via COMATE APP
PTF520 implement a cellphone setting system. Users can install COMATE APP on their cellphone or tablet and use the APP to connect with a PTF520 flow meter to read or set the flow meter.
This APP also support a remote diagnose function. Whenever there is anything wrong with the flow meter, customer can ask for a remote diagnose support. When this function is working, COMATE engineer back in office can remotely check the setting of the meter, and the signal of sensor, to provide users with most accurate trouble shooting advise.
COMATE APP has made the using of the product simple and efficient .
