Dual channel ultrasonic flow meter uses advanced ultrasonic flow/Heat measurement technology. Each channel can achieve measurement accuracy of ±1.0%. It can also be four-channel or multi-channel. The sound channels can be mutually redundant, greatly improving the accuracy and stability of the flow (heat) meter. It can effectively overcome the shortcomings of low accuracy and unstable flow (heat) caused by monophonic products that cannot adapt well to changes in the flow field.

RFQ

Dual-channel ultrasonic flowmeters and multi-channel ultrasonic flowmeters can be used as measurement standards for quantitative control. Especially suitable for flow measurement of high viscosity oils, chemical products and ultrapure water. It can also be connected to two temperature sensors and used as a flow (heat) meter.

Dual Channel Ultrasonic Flow Meter Working Principle

The transit-time ultrasonic flowmeter measures the flow rate by detecting and calculating the difference in the forward and reverse velocity of the ultrasonic pulse in the fluid.

When measuring, a pair of sensors are used to alternately transmit and receive ultrasonic waves in opposite directions. When the signal propagates in the downstream direction of the fluid, it is faster than in the counter-current direction. When the fluid is stationary, the time difference is zero.

Therefore, by measuring the propagation time of ultrasonic waves in downstream and countercurrent flow, the time difference Δ can be obtained. According to the relationship between Δt and flow velocity V, the average flow velocity of the fluid can be measured indirectly. The volume flow rate Q can be calculated based on the cross-sectional area of the pipe.

V=K△t Q=SV

formula:
K is a constant;
S is the internal cross-sectional area of the pipe.

Dual Channel Ultrasonic Flow Meter | Multi-Channels Applications

Dual-channel ultrasonic flowmeters are widely used in industrial flow measurement fields, especially in petrochemical, water treatment, food manufacturing and pharmaceutical industries.

It can measure the flow of various liquids. It has the advantages of high volume measurement accuracy, stable accuracy, and fast response speed.

At the same time, the dual-channel ultrasonic flowmeter can also achieve non-contact measurement. There is no need to install any probes or sensors in the pipeline. It can effectively avoid pipeline clogging or affecting the flow of liquid.

Dual Channel Flow Meter with Pipe Sensor

Dual Channel Ultrasonic Flow Meters sensor types and installation

Dual Channel Ultrasonic Flow Meters sensors are divided into: external clamp type, insertion type and pipe segment type. Set the sensor installation method according to different application needs.

Generally speaking, it is recommended to use the Z-type installation method for external clip-on or plug-in types. It is not recommended to use the V method for installation.
If it is a mono-channel product, you only need to install the UP1/DN1 pair of sensors in the example in the picture. If it is a three-channel or four-channel product, add UP3/DN3 and UP4/DN4 sensors in the vertical direction accordingly.
