The portable, clamp-on KROHNE UFM 610 ultrasonic flow meter provides efficient flowmetering and volume counting of clean, homogeneous liquids with low gas and solids contents with single-beam measurement.

The KROHNE UFM 610 Ultrasonic flow meter functions by mounting two ultrasonic sensors to the outside wall at the measuring point. Each sensor emits and receives sonic pulses which are then digitally converted in the signal converter. Current, frequency and status outputs are viewed via a display.

The advantages of using ultrasonic technology by taking measurements from the outside the pipe include low operating costs, low power consumption, no maintenance requirements and ease of installation. Technical advantages include non-contact with the medium being measured, no obstruction of the pipe cross-section, no additional pressure drop, no process interruption and the electrical conductivity, pressure and density have no effect on measurements.

Applications for the KROHNE UFM 610 Ultrasonic Flow Meter

  • Demineralized water for cooling purposes
  • Boiler feedwater in power stations
  • Pretreated wastewater in sewage plants
  • Checking other flowmeters
  • Oil
  • Acids
  • Alkaline solutions

Transit Time Ultrasonic Flow Meters – Technology Explained

Transit Time ultrasonic flow meters are well-suited for relatively clean fluids with low to moderate aeration. These flow meters operate by comparing the time for an ultrasonic signal to travel with the flow (downstream) against the time for an ultrasonic signal to travel against the flow (upstream). The difference between these transit times is proportional to the flow, and the flow meter converts this information to flow rate and total. With this technology, the transducers are mounted on the outside of the pipe, providing tremendous advantages over more traditional and invasive flow measurement instruments.

These benefits include:

  • no system downtime for installation
  • no system contamination
  • no pressure drop
  • no moving parts
  • no risk of leaks
  • little maintenance required
