Water Current Meter (Cup type)
The BHM-H-CM2 is manufactured for mechanical current-meter applications and is referenced to IS 3910:1992. It supports velocity-area discharge measurement workflows used for rivers, canals and open channels. The instrument is supplied with an individual calibration equation and calibration certificate, allowing measured revolutions to be converted into water velocity. It can be used with wading rods, suspension cables, hydrometric fish weights, bridge arrangements, digital revolution counters, velocity indicators and data loggers. For procurement or project submission, final compliance should be confirmed against the purchaser's exact technical schedule, required calibration authority, inspection procedure, environmental conditions and documentation format. Optional configurations or accessories should be listed separately in the commercial offer when requested.

Water Current Meter (Cup type)
What is the BHM-H-CM2? It is a vertical-axis, six-cup water current meter used to measure water velocity in rivers, canals,streams and open channels.
How does it work? Flowing water rotates the cup wheel. A magnetic reed-switch or fibre-optic sensor produces one pulse per revolution, and velocity is calculated using the supplied calibration equation.
Where is it used? It is used for river discharge measurement, canal monitoring, stream gauging, hydrological surveys, irrigation engineering, reservoir studies and hydraulic laboratories.
What is the measuring range? The stated operating range is 0.30 m/s to 3.50 m/s, with a starting velocity of 0.015 m/s.
What comes with the instrument? The standard supply includes the current meter, 1.20 m wading rod, 10 m signal cable, 10 m suspension cable, 10 kg fish weight, calibration documents, tools and user manual.
Who manufactures it? The BHM-H-CM2 is manufactured by Balaji HydroMet, India, for hydrological and water-resources field measurement applications. -
