Refining ultrasonic flow measurement
July 2001
Flow Measurement & Control
Controlotron believes that dispelling the myths surrounding ultrasonic flow measurement has been the success of its flowmeters. Incorporating a hybrid design of both transit-time and doppler into one flowmeter enables the Controlotron units to measure in almost any closed pipe liquid flow application.
Specialised transducers are selected per application specification and measurements are possible in pipe sizes from 6mm to 9 m with transducers and mounting accessories pre-determined from a selection table.
Recently the company's products have enjoyed much success on mine slurry applications in South Africa, and due to the electronics being suitable for any application, a quick change from standard transducers to specialised slurry transducers, enables the operator to accurately measure any application with a single system.
Wall thickness and flow gauges are optionally available allowing operators to determine pipe conditions prior to installation and with digital menu prompts, set-up is achieved in a short period of time.
The flowmeters are offered in various configurations ranging from standard indoor units to IP65 cases, submersible systems, single, dual or quad channel systems, thermal energy meters, leak detection and explosion-proof meters.
The meters are not limited to portable versions and fixed installations are common, especially in instances where a number of pipes are to be measured simultaneously and a single processor can accept up to four pipeline measurements.
A unique feature of the Controlotron units is the special four-beam design, which is used in applications that require high precision for use in custody transfer applications. This system has an intrinsic accuracy of better than 0,5% - which can be calibrated down to 0,2%.
Controlotron's dedication to providing nonintrusive flowmeters with increased accuracy without the need to cut or drill into existing pipe work has seen many large industries discarding previous reputations and limitations of ultrasonic flowmetering and utilising the benefits of the new available technology. Controlotron, a world-leading manufacturer and supplier of ultrasonic flowmeters, is represented locally by MeasureTech - a Tyco International company.
