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.

Charun instruments introduces process control automation solutions as a leading manufacturer and distributor of affordable & high quality electromagnetic flow meters for various industrial applications, control panel, equipments to measure flow, humidity, pressure and temperature. The flow meters are ranging from conventional to advanced ultrasonic flow meter, digital fuel flow meter and oil flow meter. Digital level transmitter, different types of level switches, level controllers, thermo-hygro meter, humidity transmitter and humidity datalogger are some of the specialized process control instruments offered with innovative features.

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.
