Pipe type ultrasonic flowmeter is composed of a main body and a pipe segment type sensor. The DN15-DN32 uses a -type pipe segment sensor, and the DN40 and above uses a standard pipe segment sensor. The pipe-type ultrasonic flowmeter has the advantages of simple installation, low starting flow, high measurement accuracy, and no pressure loss. The main unit can be installed in the wall, instrument box, and distribution box with a protection level of IP67. The external clip sensor is installed on the surface of the pipe and selects different sensors. The applicable diameter is DN15~DN6000.

Use ultrasonic flow measurement technology, no mechanical moving parts drift diameter design, no pressure loss, cut down the electric consumption of the pump and help untilities reduce cost. Features: Low in initial flowrate, and the min. Flow velocity measured is0.002 m/s; Measurement cycle 1 time per second, battery powered (One battery can work continuously for 6 years); Multi-channel construction design, double cross section measurement, and be able to ensure the measurement accuracy to the largest extent; Be able to work at any flow point for long time; IP68 of the whole meter, for each unit of the meter is IP68 designed; Micro-consumption design, less than 0.0008W; Drift diameter design, no pressure loss. Operating on velocity-difference principle, the LG-UWM68 series is specially designed for urban water supply and building-use. The conventional water meters suffer from the drawbacks that they are only operable at a higher flowrate and are insensitive to a small flowrate. However, the LG-UWM68 series water meter can help tackle the bottleneck. And the meter is highly adaptable to diversified industrial conditions Due to the use of ultrasonic flow measurement technology, it has no mechanical moving parts drift diameter design, no pressure loss, cut down the electric consumption of the pump and help the enterprises reduce cost Be able to work at any flow point for a long time and high in reliability, immune to magnetic interference Battery-powered capable of operating continuously for a period of over 6 years with a single cell High sensitive to minimal flowrate and high in measuring accuracy Capable of performing various output function, and it is capable of making wireless transmission of meter reading to form a monitoring system via the GSM network to monitoring the meter's running status and the pipe network conditions. Three design versions are available, i. e. The ordinary version, 2-way version and fire water version are cater to different needs of users Ordinary version: Measurements of the flowrate and cumulative running time in positive direction 2-way version: Capable of measuring flowrate, cumulative flowrate cumulative running time in positive/reverse direction; Fire water version: Much bigger range ratio, and specially designed for fire water. CE: 2004/108/EC The meter is in conformity with Standard on Measurement of Water Flow in Fully Charged Closed Conduits_Meters for Cold Potable Water and Hot Water GB/T 778-2007-a standard is issued by the People's Republic of China L Ex-factory calibration of the meter is made in conformity with Standard on Water Meter for Potable Cold Meter JJG162-2009- a standard is issued by the People's Republic of China.
