With a rating of 05 ultrasonic meters have no moving partseliminating driftand they eclipse the 15 accuracy of mechanical meters. In more advanced applications it can also incorporate a temperature and pressure input to determine more process variables. The recommended straight run by type is shown below.
Ultrasonic flowmeters Our product finder helps you to search for suitable measuring devices software or system components via product characteristics. Clamp-on ultrasonic sensors on the other hand are installed on the outer wall of the pipe and thus also enable temporary measurements or a retrofitting. However for more severe flow distortions you may require more.
Typically flowmeter manufacturers specify a minimum of 10 to 15 diameters of straight pipe. The ultrasonic clamp-on sensors of the KATflow series come with a standard cable length of 25 or 50 meters depending on the specific sensor type. There are two basic approaches for ultrasonic flow monitoring which apply to clamp-on and permanently mounted sensors.
As a leader in the field of clamp-on ultrasonic flow measurement FLEXIM offers the ideal flow meter solutions - even for. Clamp on ultrasonic flow meters. Installation is quite easy and operation is convenient.

There are two basic technologies. It causes no pressure drop and requires no regular maintenance.
General Clamp-on meters are specified to achieve two to three per cent uncertainty. The required straight run is depeding on the type of flowmeter. This difference can be significant for municipalities especially over time when it comes to their ability to find leaks and tackle non-revenue water NRW problems.
Flow Measurement SITRANS FS ultrasonic Clamp-on ultrasonic flowmeters SITRANS FSS200 ultrasonic flow sensor 3 Function continued SITRANS meter family description SITRANS FS230 clamp-on flowmeters The FS230 system is a basic function permanent or dedicated Clamp-on meter that is available with a full range of safety ap-provals and IOs. The principal challenge in clamp-on ultrasonic measurement is to align the transducers to maximize signal transmission between them. On applications with longer straight runs the 4-ultrasonic beam arrangement used with the F706 liquid clamp on flow meter achieves outstanding accuracy performance and repeatability making it the preferred solution for redundancy measurement check metering of custody transfer meters and leak detection applications where high accuracies are needed.
Integrated wall thickness measurement. LRF-2000S is one of the best-selling flow meters. LRF-3000S is high-end clamp-on ultrasonic flow meter.
Ultrasonic Flow Meter Types. Doppler ultrasonic flowmeters use two transducers mounted directly opposite each other. One other key advantage to this installation method is that it allows the instrument to be used in a portable.
Ultrasonic meters also have few to. This means that for a 4 diameter pipe you would need 10 x 4 40 of straight pipe or for a 2 pipe you would need 10 x 2 20 of straight pipe. Better than 02 Accuracy.
