The PT878 Clamp On Flow Meter

The Panametrics PT878 ultrasonic flow meter is a clamp-on portable flow meter which can be used to measure most liquids including clean liquids and also some liquids with solids or gas bubbles. The PT878 is suitable for use on all metals and most plastics, on a pipe range from 12.7mm to 7.6m (0.5 inch to 300 inch) without the need to cut into the pipe.

The PT878 clamp-on flow meter is ideal for rental purposes as it is easily installed, up and running in minutes and can be quickly relocated to other pipes.

The PT878 is ideal for many types of survey including:

  • Energy - When combined with PT100's the PT878 becomes a full energy meter ideal for measuring cooling and heating systems. Typically measuring energy used and lost in a variety of applications e.g. testing boiler efficiency on hot water systems, cooling system effectiveness and condensate recovery.
  • Water usage - The PT878 can be used to monitor not only water consumption but also basic leak detection. Another typical application is verifying flow rates of flow meters of different technologies e.g. e/mag, vortex and mechanical.
  • Chemical dosing - For measuring the dosage of chemicals, The PT878 flow meter is ideally suited. Whether highly acidic or alkaline due to the fact the meter is on the outside of the pipe and does not come into contact with the media, chemical compatibility or temperature is not an issue.

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.
