How Doppler Area Velocity Flow Meters Measure Flow in Open Channels and Partially Filled Pipes
Measuring flow in open channels and partially filled pipes can be challenging because the flow area changes continuously with the water level. Unlike full pipes, where the internal cross-sectional area is fixed, open channels, rivers, culverts, and partially filled pipel...Read more -
Why Accurate Flow Measurement Is Critical for Industrial Water Management
Industrial water plays an essential role in manufacturing, power generation, chemical processing, mining, food production, and many other industries. It is used for production, cooling, cleaning, boiler feed, wastewater treatment, and environmental monitoring. As water costs and environmental req...Read more -

Why Does Low Conductivity Affect Electromagnetic Flowmeter Accuracy?
An electromagnetic flowmeter works according to Faraday’s law of electromagnetic induction. When a conductive liquid flows through the magnetic field generated by the sensor, a small voltage is induced between the electrodes. The converter detects this voltage and calculates the flow velocity. ...Read more -
Why Does the Flow Signal Fluctuate Continuously?
Continuous fluctuation of the flow signal does not necessarily mean that the electromagnetic flowmeter is faulty. In many cases, the fluctuation is caused by actual changes in the flow, unstable process conditions, air bubbles, grounding problems, or electrical interference. The first step is t...Read more -
Why Does the Totalizer Accumulate Flow When the Pump Is Stopped?
If the electromagnetic flowmeter continues to accumulate flow after the pump has been stopped, it does not necessarily mean that the flowmeter is defective. The most common reason is that the sensor is still detecting a small flow signal. Even a very small flow rate, if it persists for a period...Read more -
Why Is the Flowmeter Less Stable at Very Low Flow Rates?
An electromagnetic flowmeter measures flow velocity by detecting the voltage induced when a conductive liquid moves through a magnetic field. At very low flow rates, the flow velocity becomes small, so the induced signal generated by the fluid is also very small. As a result, the measured signa...Read more
