Dalian Taosonics Instrument Co.,Ltd is proud to introduce the new revolutionary, precise and super reliable ultrasonic water meter, Which is according to the -4064 778 standard.ISO GBTThe water meter be adapted by advanced transit-time measurement technology , with the remarkable features of low power consumption, wide measuring range ratio, stable and reliable measurement.

Each components take the 68 protection class, to ensure long term operation though water in IPthe inside meter. Widely used in the urban water supply, water resources management, irrigation, landscape management, industrial production and automation industry

Protection Class 68IPWhole Machine Waterproof whole machine ：sealed completely, reach 68 protection class.IP

Parts waterproof Circuit board, transducer and ：battery also can reach 68 protection level, to IPensure long term operation though water in the inside meter

Buil t-in Batch Control lerBuil t-in Time AccumulatorSet up the time controller by automatically or manually, so as to finish quantitative water supply or quantitative irrigation automatically.

Set up the time- sharing flow accumulation at a set period t ime, to finish a gradient rate.

for the refrigeration and air-condit ion industry.

With the two way 1000 temperature transducer, PTwhich can finish the heat measurement, especially

Double beam ultrasonic sensor for high accuracy.

High Accuracy Measurement

Ultrasound Measurement,No Rotation, N o Moving PartsLong term measurement with high accuracy, stable and reliable operation.

Applicable to variety of water quality, including the gravel and weeds water quality.
