Magnetic Flow Meters
QTRD91 non-contact radar level meter principle
Ultrasonic Level Meters
Recently, my company started to produce new type electromagnetic flow meter.
This type flow meter could have 4-20mA and RS485 output, and 24VDC or 220VAC power supply.
It will be very useful for customers who only want to a output from flow meter, and don't need to read the display directly.
4 wires 4-20mA is standard funcation and customer also could choose RS485 as added funcation.
