RBBH DN50-1000 District Ultrasonic Heat (Cooling) Meter is an innovative heat meter with static flow sensor based on the ultrasonic measuring principle. RBBH Ultrasonic Heat Meter is designed for measuring the use of heating in which water is the heat-bearing medium.
RBBH District Ultrasonic Heat Meter(BTU meter) (Single, Dual and Mutli Channel ) is an innovative heat meter with static flow sensor based on the ultrasonic measuring principle. RBBH District Ultrasonic Heat Meter is designed for measuring the consumption of heat in which water is the heat-bearing medium. RBBH District Ultrasonic Heat Meter utilizes ultrasonic measuring methodology and microprocessor technology. All calculation and flow measuring circuits are designed on one single board, thus offering exceptional accuracy and reliability.
As a professional supplier and manufacturer of Ultrasonic Flow Meter and Heat Meter, RB flowmeter has been supplying quality Ultrasonic Flow Meter and Heat Meter to customers all over the world for over 15 years.
RBBH District Ultrasonic Heat (Cooling) Meter series transit time Heat flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-method in which case the ultra sound transverses the pipe twice, or W-method in which case the ultra sound transverses the pipe four times, or in Z-method in which case the transducers are mounted on opposite sides of the pipe and the ultra sound transverses the pipe only once. The selection of mounting method depends on pipe and liquid characteristics. When flow meter works, two transducers transmit and receive the ultrasonic signal which travels firstly downstream and then travels upstream (Figure 1). Because ultra sound travels faster downstream than upstream, there will be a difference of time of flight(△t). When the flow is still, the time difference(△t) is zero. Therefore, as long as we know the time of flight both downstream and upstream, we can work out the time difference, and then the flow velocity (V) and flow volume (Q) via the following formula.
