25-115mm Micronics U1000MKII-WM-FM Wall Mount Ultrasonic Clamp-On Flow Meter
The Micronics ‘Ultraflo’ U1000MKII-WM-FM Wall Mount Ultrasonic Clamp-On Flow Meter (up to 4” pipe size – 25-115mm OD) is suitable for water and glycol applications and comes with a separate wall mounted keyboard and display. This USM is a permanent/ fixed clamp-on metering solution that utilises ultrasonic technology to measure flow rate and total flow with a volume pulse output (standard) from outside the pipe. The U1000MKII-WM-FM is a great value alternative to traditional inline heat / flow meter installation for use in industries such as energy management and building services. This clamp-on meter is easy to install as it has been factory configured and, because of this, requires minimal on-site programming and functions by simultaneously transmitting ultrasound between the clamp-on transducers in both directions. When ultrasound is emitted in the direction of flow the speed of the sound is accelerated; when it is emitted in the opposite direction the speed of the sound is decelerated. The time difference between ultrasound emissions is directly proportional to flow velocity. Using the flow velocity and the pipe’s cross-sectional area, the operator can calculate the volumetric flow.
Measurement Principle: Micronics meters use a cross-correlation transit time algorithm to provide accurate flow measurements. An ultrasonic beam of a given frequency is generated and applied to the transducer crystals. This transmission goes first from the downstream transducer to the upstream transducer as shown in the upper half of Figure 1 (below). The transmission is then made in the reverse direction, being sent from the upstream transducer to the downstream transducer as shown in the lower half of Figure 1. The speed at which the ultrasound is transmitted through the liquid is increased slightly by the velocity of the liquid through the pipe. The subsequent time difference T1-T2 is directly proportional to the liquid flow velocity.
