Magnetic Flow Meters
QTRD91 non-contact radar level meter principle
Ultrasonic Level Meters
Electromagnetic heat meter
Electromagnetic flow meter is used to measure the energy for hot water or cold water.
It's high accuracy and stability measurement.
So, it's widly used in building system and factories.
This type heat meter contains two pieces of PT1000 temperature sensor.
The converter could disply both of flow rate and energy data.
The same as magnetic flow meter, it could have MODBUS communication, 4-20mA and pulse output.
