OCM F Flow Meter

Name: OCM F Flow Meter
Brand: NIVUS
Availability: InStock

The OCM F flow metering system utilises a fully bidirectional ultrasonic velocity sensor.

The intelligent Doppler sensor detects and directly evaluates the flow velocity. Other than with mag meters, this method has an absolutely stable zero point. Moreover, the dynamic measurement range for minimum level and flow is very high. Level measurement can be carried out either by a sensor-integrated pressure cell or by using an external sensor.

Operation / Programming

Thanks to the intuitive user interface it is very easy to set up the OCM F for the requirements of various applications. Additional input devices like Computers etc. are not needed. Programmed settings are indicated clearly.

Measurement principle

The measurement principle is based on the classic Doppler method where an ultrasonic signal with a defined frequency is transmitted into a liquid at a known angle. A portion of the ultrasound energy is reflected by the solid particles or gas bubbles carried with the liquid. Due to the movement of the particles a frequency distortion occurs which is direct proportional to the particle velocity. The flow velocity can be determined from this frequency shift subsequently. From the flow profile and the multitude of reflecting particles a frequency spectrum results. This spectrum, suitable for hydraulic assessment of measurement places, can be indicated on the OCM F display. The newly developed intelligent Doppler sensor directly detects and evaluates the flow velocity.

Memory

The internal memory enables storage of medium velocity information as well as temperature and flow data. With the frontside USB socket measurement data as well as settings can be read out. The free NivuSoft measurement data software enables easy visualisation of readings.
