Product Options


SONOKIT is a transit time based retrofit ultrasonic flowmeter for existing pipelines. The kit includes all necessary parts and special tools to make the installation as a 1- or 2 -track flowmeter. The set is made for installation on empty pipes or pipes under pressure without process shut-down (hot tap). The kit includes in-line transducers (in contact with media) which assure superior accuracy and performance. Please contact RS Hydro for further information on hot-tap tools and instructions.


  • Cost-effective solution - contains all the necessary components for retrofitting
  • No bypass installation necessary - withstands pressures up to 40 bar (580 psi) and media temperatures between -20 °C and +200 °C (-4 °F and +392 °F)
  • SONOKIT is easy to install in pipeline sizes DN 200 to DN 4000 (8" to 160") 1-track DN 100 to DN 2400 (4" to 96") - without process shut-down or flow interruption.
  • High accuracy - the bigger the pipe, the more accurate the result
  • Solid construction and no moving parts for a 100% maintenance and obstruction-free flowmeter
  • The SONOKIT comes with transducers in IP68 enclosure
  • Available in a robust version that can be buried and withstands constant flooding
  • In-line transducers assure superior accuracy and performance
  • FUS060 transmitter versions with HART or PROFIBUS PA
  • FUS080 transmitter, battery or mains-powered
  • Automatic calculation of the calibration factor when pipe geometry data are entered in the transmitter

No problem. The quick start guide is designed to make installing the flow meters a simple task. Everything you require for set up will be found in the peli-box supplied with the flowmeter.
Every flow meter is tested upon shipping and return as part of our ISO9001 procedure. Also, as part of this procedure, the flow meter is calibrated once a year. If a copy of the calibration certificate is needed let us know.
The flow meters typically provide an accuracy of ±1 to 2% of rate, so if you are measuring 100l/sec then the accuracy is between 98-102l/sec.
We are here to help. If the self-help and quick start guides do not help, then call one of our technical support engineers on +44 (0) 1527 882060. We have supplied and supported many clamp on rental installations throughout Europe.
If the stock is permitting, and all paperwork is received by 12pm then flow meters can usually be available the next day.
Without exception, all our flow meters are tested. If you need a 110v plug instead of the standard 230v plug let us know.
All of our standard transducers will do -40degC to +150degC, but this will depend on your application.
  • Liquid: below 50mm CFLP transducers are required, 50-1000mm CRS-402 transducers and 150-8000mm CRS-401 transducers. All the bits you need can be supplied, and delivered with the meter.
  • Gas: below 80mm CRS-402 is required, for 80-300mm the CRS-401/CRV-310 and for above 300mm the CRW-312 transducers are required.
  • High temperatures: For liquid we can measure +450degC for liquid and for gas/steam +250degC. But please consult RS Hydro.
As long as the pipe is relatively clean, coatings or paint is usually not a problem for clamp on flow meters but if the pipe is corroded or the paintwork has bubbled then a quick sanding down with sandpaper or a wire brush is recommended.
An ultrasonic wall thickness gauge, that measures to within 0.05mm, is provided as standard with all flow meter rental packages.
The screendump facility on the integrated dataloggers on all our flow meters, allows you to photograph any screen and download it to your pc.
We have hired more ultrasonic clamp on flow meters than any other company in Europe. We are now one of the world's largest distributors of GE Panametrics flow meters. We always review your application before hire so no unwanted surprises are encountered. Every effort has been made to make your flow meter hire and enjoyable experience: quick start guides to help you set up with ease, online videos for further help, rugged packaging for extra durability anywhere, and real flow engineers available for online/telephone support.
