OCM F Flow Meter

Brand: BM Technologies

The OCM F flow metering system utilizes a full bidirectional ultrasonic velocity sensor. 

Level measurement can be carried out either by a sensor-integrated pressure cell or by using an external sensor. 

The transmitter can be powered with various voltages depending on the type used.
