Ultrasonic flow meters mainly have 2 types: open channel type and transit-time pipe line type. Both of them can measure flow by transmitting and receiving ultrasound wave. There isn't a flow meter which can meet all of applications, Ultrasonic Flowmeter is a very useful measure instrument, ultrasonic flow meter is no exceptional. Users should do a right selection as the actual situation. But if possible, it is better to select digital flow meter without moving parts, e.g. ultrasonic flowmeter.

An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound
Because the ultrasonic sensor is not in contact with the water, ultrasonic sensors have no scheduled maintenance. Ultrasonic sensors are not affected by chemicals, grease, suspended solids, or silt in the flow stream.
An open channel ultrasonic flow meter is one of the most versatile, accurate measurement tools on the market today because it uses sound to determine the water level in your system. When an ultrasonic flow meter takes a reading, it emits a high-frequency sound puce towards the surface of your flow, where it will hit the water and create an echo. The flow meter measures how long it takes the echo to return to the meter, and this is how it determines the flow level.

The Transit-time pipe line type flow meter mainly utilizes clamp on flow transducers to detect flow in closed pipe. Clamp on flow meter is an unique measurement way and at present, ultrasonic flow meter is the main type with such way at present. Thus, it is very essential to know its advantages as below:
1.No Pipe Cutting
Clamp on installing way doesn't need to cut pipe. This is very different from traditional flow devices. Users just need to clamp the flow sensor to pipe surface. Then ultrasonic flowmeter can detect flow by ultrasound wave and then automatically calculate the value of flow velocity, flow totalizers, etc.
2.No Direct Contact to Fluid
Clamp on flow sensors don't need to contact fluid directly. It avoids pollution to the fluid. This can meet special requirement of food, medical, chemistry, biology, etc.
3.No Risk of Leakage
No pipe cutting means no need to damage pipe. So only pipe condition is good, clamp on flow meters won't provide a leakage possibility. This advantage is more suitable for strong acid, alkali, poisoning, corrosive liquid, etc.
4.No Moving parts
Traditional mechanical flow meters must use moving parts to ‘sense' flow. This will destroy the flow status. Meanwhile, the flow accuracy will degrade as using of moving parts.As its using, the moving parts will become bad and users have to replace a new flow measurement device.

14. Low Cost Ownership
Many users may have a first impression that advanced flow meter always has a high price. The first investigation may be higher than mechanical flow meters. But plus installing fee, life span and maintenance, its total cost is not higher, even lower.
15. If pipe contains bubbles or holes in it, clamp on meter may not work well, the open channel flowmeter could work for this condition.
