portable doppler ultrasonic flow velocity meter clamp on
GLP-1-B is a new type of non-contact flowmeter based on the principle of Doppler ultrasound, which uses a more advanced frequency difference method to process signals. It is completely installed outside the pipe, and does not need to stop and cut off the pipeline. With ultrasonic wave power adjustment function, it is very easy to solve the application problems that can not be solved by ordinary flowmeters such as super large diameter, thick pipe wall and cement lining. A unique digital filtering system and automatic identification circuitry enable the measurement system to distinguish between reasonable linear and distorted signals. This technique provides a linear measurement at the asymmetrical disturbance point, ensuring measurement accuracy that is not achievable with conventional techniques. The larger LCD screen provides more information and enables a menu-based HMI.

The working principle
There are discrete perturbations in any flowing liquid within the conduit, which may be suspended solid particles or bubbles, or interface due to fluid perturbations. This perturbation causes the reflected ultrasonic generator to generate a frequency meter Δf, which is a linear function of the flow rate. By measuring the frequency meter Δf, the flow rate of the pipe can be measured and the flow rate can be calculated.
sewage, raw water, circulating water, pulp, pulp, mud, crude oil, acid and alkali, chemical raw materials, seawater and so on. On-site flow verification; on-site verification of other flow meters.
◇ Contaminated or pure liquid can be measured, equivalent to a high-precision Doppler ultrasonic flowmeter and a high-precision time difference ultrasonic flowmeter
◇ Non-contact flowmeter, external clamp installation, no stop or stage pipeline
◇ can resist inverter interference
◇ It is very easy to solve the application problems that cannot be solved by other ultrasonic flowmeters such as oversized pipe diameter, thick pipe wall and cement lining.
◇ Built-in data logging function, can record 10 files, 65072 data points
◇ Data playback function, the flowmeter is equipped with Microsoft Windows-style graphical interface dedicated software. Through the RS-232 interface, the data can be downloaded to the computer for comprehensive analysis of the data, and the instantaneous flow time curve waveform can be displayed visually. It can extend the time axis arbitrarily, providing a powerful tool for managers to analyze data.
◇ Simplified Chinese and English bilingual windows, suitable for different user needs
◇ Built-in flow meter calibration function for quick and convenient operation
◇ It has annual, monthly and daily traffic accumulation functions, which can record the cumulative flow of the first 5 years and the current year, the first 12 months and the current month, the first 31 days and the current day.
