Product Description

The Ultrasonic Water Meter TFM6000-WF series is specially designed for urban water supply and building-use according to the GBT 778.1-2007、ISO-4064、JJG162-2009 standard. The conventional water meters suffer from the drawbacks that they are only operable at a higher flow rate and are insensitive to a small flow rate. However, the water meter can help tackle the bottleneck. And the meter is highly adaptable to diversified industrial conditions. The water meter be adapted by the company’s newly-developed unique advanced transit-time measurement technology , with the remarkable features of low power consumption, wide measuring range ratio, stable and reliable measurement.
In the structure of Ultrasonic Water Meter TFM6000-WF, the components take the IP68 program, that is, each component is of an IP68 protection level, to ensure long time operation though water in the inside meter.The wireless power and various communication interface can be matched to the meter to achieve remote meter reading. This series of water meter’s production process is automatic or semi-automatic, including automatic detection of circuit boards, the automation of the circuit board’s high-low temperature test machine, the automation of potting and calibration process, ensuring that every machines out of the factory are qualified.

Transit Time Flow

Transit Time flowmeters measure the time it takes for an ultrasonic signal transmitted from one transducer to cross a pipe and be received by a second transducer. Upstream and downstream time measurements are compared. With no flow, the transit time would be equal in both directions. With flow, sound will travel faster in the direction of flow and slower against the flow.

Very accurate timing circuits are required but 1% accuracy is quite typical when the transducers can be mounted on a pipe section with evenly distributed flow.

Because the ultrasonic signal must cross the pipe to a receiving transducer, the fluid must not contain a significant concentration of bubbles or solids (less than 2%). Otherwise the high frequency sound will be attenuated and too weak to traverse the pipe. Applications include potable water, cooling water, water/glycol solutions, hydraulic oil, fuel oils and chemicals.

Transit Time transducers typically operate in the 1000-2000 MHz frequencies. Higher frequency designs are normally used in smaller pipes and lower frequencies for large pipes up to several meters in diameter.
