1. Description
CMENTECH flowmeters use a multi-line measurement technique during passage, which is designed to accurately measure the flow rate (± 0.20 ~ 0.5% of the actual flow rate) in pipes. Depending on the accuracy requirements, the flowmeters can be configured to work with 1-10 acoustic routes.
2. The principle of measurement
This meter uses multipath ultrasonic waves to measure the average velocity of the fluid lines on the cross-sectional area of the fluid and calculates the flow volume without any coefficients, applying a double integral formula to the velocity and area distribution. (Patented) This method minimizes measurement errors due to a complex velocity profile with set conditions (near elbows, valves, pumps, etc.)
3. Features and application
a. High accuracy of measurement of Reynolds number and coefficient of friction has no effect. Errors do not occur due to the thickness of the pipe, the scale of the lining and the signal time.
b. High accuracy with short straight pipe and low flow rate.
c. With a large measurement range (maximum/minimum flow), a measurement based on the measured value (MV) rather than the full scale deviation (FS) negates the effect of the flow range.
d. Installation without stopping the flow (hot plug) and replacement of the built-in sensor. Ultrasonic transducers are directly installed in
an existing pipe without stopping the flow of liquid. This mounting method is great for large diameter pipes due to its low cost and convenience.
It can also achieve higher accuracy.
e. Calibration tests in one place (dry calibration method) have been obtained and certified by the Korean Center for Standard Scientific Research for this
функции. (KS B 5640), ANSI ASME MFC -5M (1985), ASME PTC-18 (2002), IEC 600041, ANSI /AWWA C750-03.
f. Data logging: 32,000 data (stream date, power on/off, coefficient, reset and error code).
g. Diagnostics: Empty, Power on/off, coefficient, reset and error code.
h. Automatic correction of zero flow and signal.
i. Automatic flow profile compensation for path loss.
j. Applications: circulation of tap water, wastewater, industrial water, seawater, oil, wastewater, beverages, process water and
cooling liquid, as well as cold water circulation for chemical and quiet manufacturing enterprises.
k. Warranty: one year of full labor and spare parts.
l. Price: very competitive
