OTT MFpro portable electromagnetic flowmeter

Measuring principle

Flow velocity measurement
The OTT MFpro portable electromagnetic flowmeter uses the principle of electromagnetic induction to measure flow velocity and water flow rate. The sensor emits electromagnetic waves in the water, forming a magnetic field in the surrounding water around the probe. The water flow velocity through the magnetic field is proportional to the voltage change of the probe, and the voltage change reflects the speed of the flow. The flow velocity value is then obtained through the microprocessor inside the probe.

Bathymetric survey
The OTT MFpro portable electromagnetic flowmeter has a built-in pressure sensor, which is used to measure the underwater position and indicate the correct flow depth. The measurement depth range is 0-3.05m.

traffic calculation
The flow velocity measured by the OTT MFpro portable electromagnetic flowmeter is calculated as the vertical average flow velocity using standard methods. The instrument uses the average flow velocity and the measured vertical depth to calculate the flow rate between the vertical lines, and finally accumulates them into the cross-sectional flow rate. Corresponding standard methods can also be used for pipeline flow calculation. The calculation methods for average flow velocity and flow rate follow corresponding international standards.
