Magnetic Flow Meters
QTRD91 non-contact radar level meter principle
Ultrasonic Level Meters
High pressure battery power electromagnetic flow meter
My company could produce magnetic flow mete with 3.6V battery power.
It has special designed coil in flow sensor.
The battery could work at least five years.
This produced battery power magnetic flow meter has high pressure design also.
The flange is DIN PN420.
This type flow meter is used to measure slurry or mud normally for oil field or construction.
