1.Introduction
The TY3 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, 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.
2.Features
Double beam ultrasonic sensors for high accuracy and reliable operation
Less than 0.01 m/s starting velocity
Multi line 9 digital LCD accumulative flow and 4 digital for instantaneous flow
Automatic power saving function under the empty pipe or long-term fluid stationary state
IP68 protection, ensure long-term operation though water in the inside meter
Date cumulative record and data acquisition function
