The insertion ultrasonic flowmeter is composed of a main machine and an insertion sensor. The plug-in sensor can be installed only by opening two mounting holes in the pipe surface. Using the hole opening tool, the plug-in ultrasonic sensor can be installed without stopping water. Because the sensor is in direct contact with the fluid, the measurement is stable and reliable.
Insertion type ultrasonic flowmeter installation precautions:
1, enough straight pipe section
Because of the strong signal of the plug-in ultrasonic meteorometer, as long as the instrument meets the straight pipe section, it can ensure the normal operation of the instrument, but the premise of this requirement is that the front 10 times straight pipe section is a non-pump outlet, not fully opened valves, etc., otherwise the flow layer of the fluid is not evenly distributed, and the instrument cannot work normally.
2, choose the appropriate installation position
The plug-in sensor should be installed as far as possible on the front line of the pipe surface, avoiding the upper end of the bubble or the bottom of the sediment. Generally installed in a horizontal, inclined or vertical pipeline, the vertical pipeline should be selected to flow from the pipe section on the lower coin to prevent non-full pipe flow at the measuring point.
3. Good pipeline condition
Before installation, it should be clear that the inner wall of the pipeline to be measured, the inner wall should not have serious condensation, rust alone, scaling and rough surface corrosion layer, both the transmission of the jump signal, but also affect the size of the pipe diameter, this size change of 1%, will cause the volume flow of 2% error. Therefore, the selection of no scale, no rust pipe section as the measuring point is the basic guarantee of the measurement accuracy of the instrument.
