Dalian Teren Industry Instruments Co,Ltd
The Teren-UFM-100F flowmeters are ideal for process-control or flow measurement at fixed locations. Their non-invasive nature makes them indispensable in applications such as chemical liquid processing, hygienic process monitoring, high-pressure flow measurement, etc.
Benefited from our advanced digital signal processing technology, the flowmeter works reliably in both clean and opaque liquid flow. Examples of applicable liquids are:
1 water, including hot water, chilled water, city water, sea water, etc.
2 sewage, waste treatment, etc.
3 oil, including crude oil, lubricating oil, diesel oil, fuel oil, etc.
4 chemicals, including alcohol, acids, etc.
5 solvents
6 beverage, food and pharmaceutical processors where non-contact is a must
Measurement Principles
The Teren-UFM-100F flowmeter is based on transit-time measurement principle, as shown in the following figure.
A typical transit-time measurement system utilizes two transmitter and receiver. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The flowmeter operates by alternately transmitting and receiving a coded burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe.
The transducers can be mounted in three methods, Z-method, V-methods and W-method, depending on pipe size. Z-method is used for large pipe. The two transducers are installed on opposite of the pipe. V-method is used for medium size pipe. The two transducers are on the same side, thus the sound transverses the flow twice. W-method is usually used for small pipe. The sound transverses across the flow four times.
