Hach FH950 Handheld Portable Flow Meter
McCrometer Hach Flow Solutions FH950 Handheld Portable Flow Meter for Velocity and Level Measurement
Able Instruments are McCrometer’s Exclusive UK & Ireland Representative for the Hach FH950 Handheld Portable Flow Meter, part of the Hach Flow Solutions portfolio by McCrometer. The FH950 is a lightweight, battery-powered handheld instrument designed to provide accurate velocity and level measurements for wastewater, collection system, and environmental flow monitoring.
The FH950 is intended for field-based measurement tasks where speed, repeatability, and confidence in results are critical. It enables users to determine stream velocities for discharge measurements, calibrate area velocity flow meters, and verify primary devices such as weirs and flumes. This makes it well suited to temporary measurements, site verification, and profiling work where permanently installed monitoring instrumentation is not required.
Key Features:
- Handheld portable design: Lightweight, battery-powered instrument for field-based velocity and level measurements.
- Electromagnetic sensor technology: No moving parts, removing the need for mechanical maintenance.
- Velocity and level capability: Available in velocity-only or combined velocity and level measurement configurations.
- Reliable in challenging conditions: Designed for use at low velocities, in shallow water, and in turbulent or debris-laden flows.
- Field verification and profiling: Suitable for discharge measurements, flow profiling, and verification of primary devices such as weirs and flumes.
- Sunlight-readable display: Transflective colour LCD supports clear viewing in outdoor environments.
- Internal data storage: Stores velocity and level measurements for later retrieval and analysis.
- Simple data transfer: USB connectivity allows straightforward download of stored data to a PC.

The sensor design and flow characteristics are engineered to deliver reliable measurements at low velocities, in very shallow water, and in turbulent flow conditions. The FH950 is also specified to take accurate readings in sediment, weed, or organic debris-choked water, supporting use at challenging sites where conditions can vary over time.
For practical field operation, the FH950 uses an easy-to-use, menu-driven user interface with a transflective, sunlight-readable colour display. The meter can store both velocity and level information internally, with straightforward data transfer to a PC via USB to reduce manual data handling.
The FH950 uses an electromagnetic sensor with no moving parts, removing the need for mechanical maintenance. The sensor is available with velocity-only or combined velocity and level capability, with an optional pressure cell available for automatic level measurement and sensor positioning during use.
