Water Flow


MF Pro

MF Pro

The OTT MF pro is a highly portable magnetic-inductive flow meter designed to spot check the velocity of:

• Streams
• Smaller Rivers
• Canals
• Measurement Flumes
• Open Channels

The system consists of a robust handheld display unit combined with a compact & light weight velocity sensor.  Both system components operate reliably in rough environmental conditions and are designed to be attached to conventional wading rods.


OTT MF Pro:  Overview



MF Pro


Discharge Automatically Calculated
The OTT MF pro computes discharge automatically based on USGS and ISO methods, saving time and eliminating potential for error caused by hand written transcription.

Real-Time Velocity
Velocity is graphed in real-time on the meter’s color display, allowing trends to be visualized quickly.

Maintenance Free
The electromagnetic sensor head has no moving parts and is virtually maintenance-free.

Versatile Applications
The sensor’s magnetic inductive measurement principle makes this unit ideal for use in low-flow conditions and environments heavy in organic matter, unlike mechanical or acoustic meters.

User Friendly Handheld Display
A lightweight, water-resistant handheld features a full color display that is easily readable even in bright sunlight.

Depth Sensor
Optionally included in the unit.
