NOTES: Next day delivery on the PT900 is available to mainland UK when rental paperwork is received by 12 midday (stock permitting).

The PT900 clamp-on flow meter supersedes the successful PT878, and builds on its usability, powerful processor and ruggedness . It benefits from a long battery life, versatility, quick clamp system and a large internal memory making it the ideal portable flow meter for a wide range of applications.

We stock a wide range of accessories and ancillary equipment to be used with the PT900 to suit your application needs.

Our rental PT900s are supplied with the tablet to make programming even easier.

How the PT900 improves on the PT878

  • Improved battery life
  • New quick clamp system
  • Bluetooth capability (program the meter from your phone or tablet)
  • New improved user interface

Suitable for many types of survey including:

  • Energy usage surveys - the PT900 can be combined with an energy kit to make a full energy meter for measuring energy used and lost in heating and cooling systems.
  • Leak detection and water usage surveys - the PT900 can be used for monitoring water consumption and for basic leak detection. It can also be used for checking the accuracy of flow meters of different technologies e.g. electromagnetic, mechanical and vortex.
  • Chemical dosing - to measure the dosage of chemicals. As there is no contact with the chemical, chemical compatibility or temperature does not cause an issue

Our Rental Service

Whatever your experience with ultrasonic flow meters, we are confident that our quick start guides and technical support engineers should be able to get you up and running in minutes. The new and improved user interface makes it easier than ever to program the meter for your application. The app even has a range of instruction videos should you need any extra guidance.

No, all of our flowmeters are competitively priced and rental is an ideal option for cutting costs to a fraction of a full priced new 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.
First, contact us for a quote. If you are happy with the quote then send us a purchase order. Or alternatively call us with credit card details and fill out and send us a rental agreement form.
If the stock is permitting, and all paperwork is received by 12pm then flow meters can usually be available the next day.
The minimum hire period for flow meters is one week.
Once you have the meter you can rent it for as long as you need it. However, it would help if you can let us know that you wish to extend the rental period. Upon return the meter is off-hired and once checked and tested, an invoice will be issued to you. Also, if you extend your rental past a 4, 8 or 12 week rental threshold, then you are entitled to a discount.
You are only charged for the period of time for which you have the flowmeter. So, if a flowmeter is returned 3 days late you are only charged for 3 extra days, and each of these days is charged at one fifth of the weeks hire cost.
Normally, you will use your own courier but if you have any problems let us know and we can arrange a pick up the day after you notify us, but you will be charged for the carriage and this cost will be added to the invoice.
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.
After the equipment has been shipped, it is the responsibility of the hirer. However, in our experience it is rare that any of our flow meters are damaged. Our flow meters are tough, as well as accurate, and reliable.
