Advantages of Doppler ultrasonic flowmeter
The traditional electromagnetic flowmeter is very complicated in the installation and use of the operation, the pipe segment sensor needs to be added to the pipeline before the pipeline is installed, once it is damaged or never installed, it must be sawed open, which also needs to throttle the pi...Read more -
When installing ultrasonic flowmeters, what factors can not be ignored ?
Ultrasonic flowmeter is a kind of flow measuring instrument, the use of ultrasonic pulse in the flow through the two directions of the velocity difference, to find the flow of fluid, is a new type of ultrasonic flow meter successfully developed on the absorption of many advantages of ultrasonic f...Read more -

When installing ultrasonic flowmeters, what factors cannot be ignored ?
Ultrasonic flowmeter selection installation point must consider the following factors: full pipe, steady flow, scaling, temperature, pressure, interference and so on. 1. full pipe: Choose a pipe section filled with fluid material uniform quality, easy to ultrasonic transmission, such as vertical ...Read more -
What factors will the measurement result of transit time clamp-on ultrasonic flow-meter be affected ?
Old pipe and heavily scaled inner pipework. The material of the pipe is uniform and homogeneous, but this kind of pipe is with bad acoustic-conductivity. Painting or other coatings on the outer wall of the pipeline are not removed. The pipe is not full of liquids. A lot of air bubbles or impurit...Read more -
What is the Scale Factor function ?
This function can be used to make the Doppler flow meter system agree with a different or reference flow meter, or to compensate for an installation where there is inadequate straight pipe to obtain a laminar flow profile, by applying a correction factor/multiplier to the readings and outputs. Th...Read more -
Why does transit time insertion sensors adopt Z method instead of V method?
There are four ways to install transit time ultrasonic sensors, V method and Z method are commonly used, and Z method is used to install transit time insertion sensors on site. This is mainly due to the insertion type sensors installation characteristics and Z method signal transmission mode. Whe...Read more -
Why should ultrasonic flowmeter sensors not be installed at the top or bottom of the pipe as much as possible?
When measuring the flow of liquid, because the liquid contains a certain volume of gas, when the fluid pressure is lower than the saturated vapor pressure of the liquid, the gas will be released from the liquid to form bubbles accumulated in the upper part of the pipeline, the bubble has a great ...Read more -
What pipes and what medium Lanry brand insertion ultrasonic flow meter can measure ?
In general, insertion ultrasonic flow-meter doesn’t have special requirements for measured pipes. For weldable metal pipelines, insertion sensors can be weld directly into the pipe. For non-weldable pipework, it needs to be installed by hoop. What medium can be measured for Lanry brand ...Read more -
What kind of pipes Lanry clamp on type ultrasonic flow meter can measure ?
Clamp on ultrasonic flow meter measures pipe material which must be uniform and homogeneous, such as HDPE, PE, PVC, carbon steel, stainless steel, aluminum, cast iron, copper, and other pipes. It can’t measure these pipes like fiberglass, asbestos, nodular cast iron and other similar pipes. It is...Read more -
What is the difference between the reading accuracy of the flowmeter and the full scale accuracy?
The reading accuracy of the flowmeter is the maximum allowable value of the relative error of the meter, while the full range accuracy is the maximum allowable value of the reference error of the meter. For example, the full range of the flowmeter is 100m3/h, when the actual flow is 10 m3/h, if ...Read more -
What are the meaning of repeatability, linearity, basic error,additional error of flow meter?
1. What is repeatability of flowmeters? Repeatability refers to the consistency of results obtained from multiple measurements of the same measured quantity by the same operator using the same instrument in the same environment under normal and correct operation conditions. Repeatability indicate...Read more
