Clamp on flow meters use Transit Time and Doppler technologies for accurate flow measurement that is non-invasive. Both technologies require two transducers that are installed to the outer surface of the pipe. T&D together with Micronics are able to offer a range of clamp-on ultrasonic flow meter solutions using both Transit Time and Doppler technologies for a range of different applications.
One of the transducers transmits the ultrasonic signals whilst the other receives them.
These transducers are used to create pulses which pass through the pipe.
A clamp on flow meter can accurately measure the flow by calculating the differences in ultrasonic signals of the flowing liquid.
Installing Micronics U1000 Clamp On Flow Meter To Pipe
Micronics specialise in using these technologies to suit most liquid flow requirements.
The Micronics U1000 is a fixed clamp-on flow meter solution for measuring preset flow rate – l/m with a volume pulse output in litres and with a 4-20mA flow rate signal, which can be used as a stand alone meter or as an integral part of an aM&T or BEM’s system.
Micronics Ultraflo clamp on flow meters are simple to install as they easily clamp on to the pipe without requiring the use of any specialist tools.
The Micronics U1000 provides a non-invasive and cost effective flow measurement solution compared to an in-line meter option.
There is minimum downtime for installation or maintenance so there is no interruption to the process.
Compact, rugged and reliable, the U1000 clamp on flow meter has been designed to provide sustained performance in industrial environments.

by Katronic, a specialised UK manufacturer of Clamp-on Ultrasonic Flowmeters.
In this following article, we consider the pros and cons of installing ultrasonic clamp-on or electromagnetic (magmeter) type flow meters. We apply some cost-benefit analysis to establish conclusive evidence of the value-engineering savings and ROI to be derived from the specification and installation of ultrasonic clamp-on flowmeters.
Call T&D for Katronic Flowmeters
A magnetic flow meter (magmeter) would be expected to give an accuracy of anywhere between 0.15% and 2% depending on the manufacturer and the application requirements. Katronic ultrasonic flowmeters have an accuracy of 1-3% of measurement.
The range of a magmeter would be anything from 5mm to 2m depending on the supplier.
Ultrasonic flowmeters cover a range of 10mm to 3.5m with only two different sensor types.
The lowest cost magmeters start at > £1,000.00 but can exceed up to £20,000.00+ depending on the size of the pipe. Clamp-on flowmeters would cost between £ 3,000 and £ 6,000.00 depending on the meter configuration required.

Magmeters cover a large range of liquids, however the medium MUST be conductive. One of the biggest problems with these type of flowmeters is that they are not able to measure liquids such as hydrocarbons and condensates. Ultrasonic flowmeters will measure virtually any liquid provided that the solid or gaseous content is not too high.
Also unlike magmeters the pipe condition does have an effect on performance.
Information available on magmeters would indicate a flow velocity range of 0.5 m/s – 10 m/s.
Katronic ultrasonic flowmeters cover a flow velocity range of 0.01 m/s – 25 m/s.

Magnetic flowmeters are an in-line device and therefore are susceptible to pressure changes and do cause a pressure drop across the meter. Clamp-on flowmeters are completely independent of pressure.
It is essential to break into the flow line to fit a meter and it may be necessary to weld flanges onto the pipeline. The fitting of an electromagnetic flowmeter is costly, both in material and manpower and involves shutting down the process which would be costly and is sometimes impossible.
Clamp-on ultrasonic flowmeters are completely free from installation and commissioning concerns and involve zero shut down time.
No Cutting. No Welding. No Cost.
Magnetic meters can be susceptible to damage and loss of calibration owing to particulate in the liquid and the general process condition. It would be recommended to remove the flow meter for checking on a regular basis thus incurring additional shut-down and cost. This is not required with the Katronic range of clamp-on meters.
