Micronics flowmeters used for R&D projects on ocean going cruise ships 

Several Micronics PF D550 Doppler Flow Meters have been used by a leading global firm that specialise in complete lifecycle solutions for the marine, offshore and energy markets. Over the past year for a number of projects on cruise ships, the PF D550 Doppler Flow Meter has been used to identify the flows coming in and out of the company’s systems. Earlier in 2017 Yvan Kursner a Process and Commissioning Engineer wanted to evaluate how far out the flow was from their standard models. A colleague of his had hired the Micronics unit on several occasions over the past year and had found the results supplied accurate and useful so the decision was taken to purchase 3 outright.

doppler flow meter - D550The PF D550 is used to monitor and balance flow, or to troubleshoot flow problems in full pipes. It is ideal to evaluate performance of in-line flow meters and can be installed, calibrated and started-up in minutes. It is particularly useful in projects where a permanent flowmeter is not required or to temporarily replace installed flow transmitters. Yvan was particularly impressed by the accurate measurement of flow. It simply needed to be clamped onto the outside of a pipe meaning that the ships’ timetable was not interrupted when installing it. Because the sensor is mounted on the outside of the pipe, there is no contact with the moving fluid. The ultrasonic sensor straps onto the outside of pipes and measures flow in any pipe that conducts ultrasound. The PF D550 ultrasonic sensor injects high frequency sound through the pipe wall and into the flowing liquid. Gas bubbles or solids suspended in the liquid reflect the ultrasonic signal back to the sensor. When this sound is reflected it is returned to the sensor at an altered frequency. This frequency shift is called the Doppler Effect. The PF D550 continuously measures the change from its transmitted frequency to the received frequency to accurately calculate flow.

Yvan is very enthusiastic about the Doppler Flow Meter. “The data supplied has been so reliable that I have personally recommended the unit to a Chief Engineer on another cruise ship.”
