Overview
Handheld electromagnetic water flow meter with automatic discharge calculation
The OTT MF Pro is a user-friendly, low maintenance electromagnetic current meter for cost-efficient 
in-stream discharge measurement.
The OTT MF pro saves time in the field by automatically calculating discharge and its 
electromagnetic sensor head is maintenance-free, ideal for use in low-flow environments, and 
unaffected by large amounts of organic matter.
Advantages
• 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 written 
transcription
• 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 the OTT 
MF pro ideal for use in low-flow conditions and environments heavy in organic matter, unlike 
mechanical or acoustic meters
• User-friendly handheld: 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
