Transducer Installation
1. point selection
Ultrasonic sensor installation should avoid the location of the clock 6 points, 12 points, so as to avoid the bottom of the pipe sediment or the upper part of the pipe bubbles, air pockets cavity caused by the signal attenuation. Give full consideration to the structural condition of the inner wall of the pipe, try to choose the pipe section without scaling for measurement, can fully meet the need to put If it can be fully satisfied, the scale should be considered as lining in order to get better measurement accuracy.
2. Measurement position selection
3. Transducer installation method
- Z-installation method: generally suitable for the pipes above DN100mm
- V-installation method: generally suitable for the DN20-300mm pipes
- W-installation method is usually used for pipes of DN10- 100mm.
Packing list
- Flow meter host: can display instantaneous flow, flow rate, and cumulative value; support 4-20mA, pulse output, RS485 communication, etc.
- Sensor probe: Including upstream and downstream sensors, standard cable length of 9 meters, can do IP68 submersible type probe.
- Pipe clamps: sensor fixed on the pipe using accessories, standard.
- Coupling agent: Squeeze the air bubble between the sensor and the contact pipe to improve signal strength and accuracy.
FAQs
Q1: Can an ultrasonic flow meter have perfect accuracy?
A1: In an ideal world, the flow readings from your process meter would be exactly correct, without any type of deviation. Unfortunately, this is not the case, and the errors inherent in measurement must always be identified, accounted for, and minimized as much as possible.
Q2: Does an ultrasonic flow meter need to be calibrated?
A2: During the production of a flowmeter, several steps are required such as coil winding, lining processing, and electrode assembly. This series of operations can cause a certain amount of error and dispersion in the device, so a calibration process is required to correct the accuracy.
Q3: Do ultrasonic flow meters have temperature compensation?
A3: Yes. As long as these temperature variations are within the temperature compensation range, the output reading compensates for the temperature variations.
Do I need to filter the gas entering the meter?
Yes. These meters use a tiny sensor element that is exposed to the gas stream. If this sensor is contaminated, the accuracy may be permanently altered and the sensor may be damaged. It is recommended that a HEPA-rated filter be used upstream of the flow meter. Important: If If you always use clean gas, your flow meter will remain stable and accurate.
