Understanding and Working Principles
Ultrasonic Flowmeter is a tool used to measure the flow (Discharge) Liquid / Liquid or Gas.
The working principle of ultrasonic flowmeter is to use sound waves / ultrasonic sound
Ultrasonic Flowmeter Reading Method
Ultrasonic Open Channel Flow Meter
As the name suggests, this method is indeed used for open / non-pipe flows, such as rivers, irrigation canals and others
It works using ultrasonic reflection to determine the distance from the face of the ultrasonic transducer to the surface of the liquid
The difference in the time taken when the signal is transmitted and when the signal is received determines the liquid level
This height will be converted into discharge / flow,
By calculating the flow height with the size / dimensions of the open channel plate that has been determined during installation
Installation
Clamped-on where the installation is placed outside the pipe
Clamped-on Portable - Handheld type
Inline where the installation is placed together with the pipe using flanges
Insertion where this method is almost the same as the inline model
Open Channel, Above the plate that has been determined the dimensions
Advantages of Ultrasonic Flow Meters:
1. No Pressure Loss: The pressure does not decrease after the liquid passes through this flowmeter, because the sensor has no moving parts and blocks the flow
Even for the clamp on and open channel mounting method the sensor does not come into contact with the fluid
2. Easy Maintenance, so for low maintenance costs
3. Available portable models are suitable for under everywhere for analysis and diagnosis in the field.
4, clamp on if applied to a large pipe size above 10 inches will be more economical than other types of flowmeters.
5. Practical Installation, because there is no need to cut the pipe or make holes in the pipe for the clamp on version,
6. Safe because it does not come into direct contact with liquids/gases that may contain hazardous chemicals
7. Sensors are more durable
