Velocity Meter

The OPMV Series velocity meter uses the Faraday's law of electromagnetic induction. The conductive liquid cut the magnetic line and cause induced electromotive force when the flow direction is perpendicular to the magnetic field lines in the alternating magnetic field, the force is correlated to the flow velocity. Powered by batteries, its advantages include simple installation, portability, and adaptability for various fluids.

Product Features

The OPMV Series velocity meter is portable instrument flow designed for the flow velocity/rate measurement. It’s professional for agricultural irrigation, hydrologic monitoring, river flow monitoring, municipal water.

The low-power design and full digital signal processing technology make measurement more stable and reliable. The range is wide and high accuracy. It widely applies to the measurement of flow velocity and rate for industry requires moving frequently such as agricultural irrigation, hydrology and water conservancy.

No movable parts, no winding. No choked flow, no maintenance, avoid troubles of other calibration and testing.

Micro-power design can last 80 hours when replace the battery. (Model II, optional level sensor).

LCD big screen back light display shows measuring data clearly in sunlight and under dimmed conditions.

The instrument interface display velocity, flow (Model II), accumulative total (Model II), level (Model II), flow direction, electric quantity, alarm information, running time, running status.

Simple operation, wading rod measurement, wire measurement and sailing measurement are available choice.

Auto power shut off.

products Application

The OPMV Series electromagnetic velocity meter is a popular choice for measuring the flow velocity of open channels, rivers and streams.

Besides the velocity measurement capability, it is also able to measure the water depth. It is a suitable instrument for measuring the flow volume of open streams and weirs.

The OPMV series velocity meter is used in the below industries:

River monitoring
Resource Management
Irrigation
