- 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.
- 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
- 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 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
