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 -
How to implement NB‑IoT communication for ultrasonic water meters?
The NB‑IoT communication of an ultrasonic water meter is implemented based on the end‑to‑end cloud‑pipe‑end architecture. The entire process includes four key steps: 1. Terminal-side measurement and data collection The ultrasonic water meter uses the time‑difference method (ToF) to measure flow: ...Read more -
Mass flow meter introduction
A mass flow meter directly measures the mass flow rate of fluids, rather than volumetric flow. Most common type is the Coriolis mass flow meter. Features: High accuracy: Typically ±0.1% ~ ±0.2% of rate, much higher than turbine or vortex meters. Measures mass directly: Not affected by temperature...Read more -
turbine flow meter working principle
The turbine flow meter operates based on the turbine principle. When the fluid flows through the turbine housing, it impacts the blades of the internal rotor, causing the turbine to rotate.The rotational speed of the turbine is proportional to the volume flow rate of the fluid. As the turbine rot...Read more -
What is the working pressure and temperature range of turbine flow meters?
The working pressure and temperature range of the turbine flow meter are as follows: Working pressure: Standard type: up to 1.6 MPa (16 bar) High pressure type: 2.5 MPa, 4.0 MPa, 6.3 MPa (25 bar, 40 bar, 63 bar) Higher pressure can be customized according to requirements. Medium temperature range...Read more -
What is the difference between turbine and vortex flow meter?
The main differences between turbine flow meters and vortex flow meters are as follows: Measurable media Turbine: Only for clean, low‑viscosity liquids (water, diesel, oil, etc.) Vortex: Can measure liquid, gas, and steam Accuracy Turbine: Higher accuracy, generally ±0.2% ~ ±0.5% Vortex: Medium ...Read more -
What media can this turbine flow meter measure?
