Where do the sensors go?

Generally on the pipe…. However we do recommend that you install the sensor at least 10 times the diameter away from bends, T pieces, flanges, joins, pumps etc. Eg: If you pipe is 50mm in diameter, in an ideal application you should install the sensors 500mm away from any obstructions.

What happens if I get the pipe size wrong?

This will affect the volumetric reading. 1mm out on a 50mm pipe is the equivalent to 4% of the overall area, whereas 1mm on a 200mm pipe is only 1%. The instrument measures the flow velocity and then calculates the volumetric reading by the pipe information entered. If this is incorrect the volumetric reading will […]

Should I be using Doppler or Transit-Time?

Doppler As we always say “Doppler does Dirty” A Doppler flowmeter bounces signals off small particles or bubbles in the moving fluid, creating a “Doppler Shift” in the returned signal frequency. The flowmeter measures the Doppler Shift then calculates the resulting speed of the reflective particles, multiplies that value by the internal diameter of the […]

How often do your flowmeters need calibration?

All units come with a 12 month factory calibrated certificate, but we recommend sending it to us once a year.

How much grease/couplant gel do I use to apply each transducer?

On small pipes use only a thin pencil line of grease along the length of each transducer face. On larger pipes with ‘M’ and ‘K’ transducers more couplant may be used. It also needs to be applied along the length of the transducer, and applied as it comes out of the tube almost as if […]

How do I find the wall thickness?

If you’re not able to access site design drawings, pipe tables, manufacturer’s part numbers or the same pipework elsewhere on site, the alternative is an ultrasonic thickness gauge which may be hired or purchased through Flowservices.

How do I find the pipe diameter

The outer pipe diameter or ‘OD’ may be stamped or sprayed onto the pipe or flange. Where this is not the case a simple tape measure will suffice in measuring the circumference. We also supply really easy to use diameter tapes. Contact us to see how you can get your hands on one.

Does your flowmeter work on flexible hose?

Although we have had some success using our flowmeter on flexible hose, we would not recommend trying to go down that route again. We normally request a spool section to be made up and installed for accurate results.

Do your flowmeters work on a concrete lined pipe?

Yes! As far as we know, Flowservices is the only company that can successfully and accurately measure a concrete lined pipe!
