For electromagnetic flow meters, what working conditions are respectively suitable for rubber lin...
1. Rubber (Natural/Neoprene/CR) Best for: General‑purpose, low‑to‑moderate corrosion, aqueous media, and slurry with mild abrasion. Temperature: Typically ‑10 °C to +80 °C (short excursions to 90 °C). Corrosion: Resists fresh water, wastewater, seawater, sewage, weak acids/bases (pH 4–10), and oi...Read more -
Why Electromagnetic Flowmeters Cannot Be Installed at the Highest Point or Downward Slope of the ...
Electromagnetic flowmeters (EMF) work based on Faraday’s Law of Electromagnetic Induction, which requires that the measured conductive liquid must fully fill the pipeline and flow stably through the sensor’s magnetic field. Only in this way can the electrodes accurately detect the ind...Read more -

Hydrostatic Level Meter Introduction
The hydrostatic level meter works based on the hydrostatic pressure principle of liquid. It calculates the liquid level height by measuring the static pressure generated by the liquid column, following the formula P=ρgh. It is mainly divided into submersible type, single flange type and double fl...Read more -
Differences Between Ultrasonic Level Meter and Static Pressure Level Meter
1. Working Principle Ultrasonic Level Meter Adopts non-contact measurement. The sensor emits ultrasonic pulses, which reflect back when they hit the liquid surface. The controller calculates the liquid level height by measuring the travel time of the sound waves (based on the speed of sound in ai...Read more -
What are the limitations of clamp-on ultrasonic flow meter?
Clamp-on ultrasonic flow meters have clear application limitations as follows: Strict requirements for liquid medium They only work well with clean, single-phase, low-viscosity liquids. Not suitable for high-viscosity media, oil-water mixture, liquids with excessive air bubbles, suspended solids,...Read more -
Can clamp-on ultrasonic flow meters be used for high temperature liquid?
Clamp-on ultrasonic flow meters can measure high-temperature liquids, but it depends on the sensor type and working temperature range. The standard normal-temperature sensors are only suitable for liquid temperature from -35℃ to 85℃. They cannot be used for high-temperature media, because high h...Read more -
Why does the ultrasonic flow meter show unstable reading or no signal ?
There are main common reasons causing unstable readings or no signal for clamp-on ultrasonic flow meters: 1. Excessive air bubbles or suspended solids in the liquid Too many bubbles, sediment or impurities will scatter and attenuate the ultrasonic wave, leading to signal loss and fluctuating flow...Read more -
How does the flow rate affect the accuracy of ultrasonic flow meter ?
The flow rate directly impacts the measurement accuracy of clamp-on ultrasonic flow meters in the following ways: Low flow rate / Below starting flowWhen the flow velocity is too low, the ultrasonic time difference becomes extremely small. The signal resolution drops easily, causing low accuracy,...Read more -
Does ultrasonic flow meter require straight pipe installation?
Yes, clamp-on ultrasonic flow meters strictly require straight pipe sections to ensure stable flow profile and accurate measurement. Standard Straight Pipe Requirement Upstream (before sensors): 10 times pipe diameter (10D) Downstream (after sensors): 5 times pipe diameter (5D) Extra Straight Pip...Read more
