Ultrasonic Flow Meter - Clamp on Type
- The ultrasonic flow meter provides numerous advantages over other types of flow measuring meters. The main advantage provided is ultrasonic measurements are non-invasive. The flow of fluid is measured by clamping a set of transducers on a pipe. Because in most cases the transducers are placed on the outside, they do not come in contact with the fluid.
- There are multiple industrial applications that call for the accurate flow measurement. However, traditional methods aren't always an option, hence the need for non-destructive, non-invasive technologies and methods. Ultrasonic flow meters are the equipment of choice whenever the contact with the measured fluid isn't possible. Ultrasonic measurements are made by attaching two transducers onto the outside of a pipe.
- This installation method is perfect for all situations in which neither cutting the pipes nor the shutting down of the process aren't possible. These externally applied flow meters don't suffer any mechanical wear and tear. They don't cause the pressure to drop, and they can be used for bidirectional measurements.
- This method is different than other flow meters. It is perfect when an application cannot be shut down or a pipe cannot be cut during installation. No pressure drops are experienced with clamp-on flow meters. The flow meter will not suffer normal wear and tear. Bidirectional measurements can be done with clamp-on flow meters. There are two types of ultrasonic technologies, Transit-time and Doppler techniques.
- Transit time ultrasonic flow meters measure the time difference between the ultrasonic pulse going upstream and the one propagating downstream. These sound waves are generated by a pair of transducers. The difference between the two intervals of time is a function of flow direction and velocity, and it represents an accurate measure for the average velocity of the liquid flowing through a pipe.
- The velocity of the fluid is indirectly measured by beaming an ultrasonic pulse from one transducer to the second one, and then back again. The time needed to arrive is measured in both situations. The difference between these two amounts of time is directly proportional to the mean velocity of the liquid. This is the parameter being used by ultrasonic flowmeters to calculate the liquid flow rate. These calculations take into consideration some user-entered data, as well.
