Gmf200-D Ultrasonic Flow Meter

An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow or by measuring the frequency shift from the Doppler effect. Ultrasonic flow meters are affected by the acoustic pr

Product overview
Hand-held ultrasonic flow meters enable non-contact measurement of liquid flow. The flow is measured by mounting the sensor on the outer wall of the pipe. It has the characteristics of small size, convenient carrying and accurate measurement. It is widely used in tap water, heating, water conservancy, metallurgy, chemical, machinery, energy and other industries. It can be used for production monitoring, flow verification, flow inspection, water balance adjustment, energy saving monitoring, and is an essential tool for real-time flow detection.

RBFM Hot-tapped Insertion Transit-Time Ultrasonic Flow meter provides abundant capabilities for accurate liquid flow measurement from outside of a pipe.

It utilizes state-of-the-art technologies on ultrasonic transmission /receiving, digital signal processing and transit-time measurement. The proprietary signal quality tracking and self-adapting technologies allow system to optimally adapt to different pipe materials automatically.

Due to hot-tapped mounting of insertion transducers, there is no ultrasonic compound and coupling problem; Even though the transducers are inserted into pipe wall, they do not intrude into the flow, thus, do not generate disturbance or pressure drop to the flow. The insertion (wetted) type has the advantage of long-term stability and better accuracy.

Product overview
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~DN6000mm.
