|DOPPLER FLOW METER CASE STUDY
Sonic-Pro Doppler flow meter serves multiple applications.
At the Del Monte tomato processing plant in central California, project engineer Richard Koch needed to obtain flow measurements at
various locations around the facility to ensure the proper function of critical system components. The numerous applications
included the effluent, KOH caustic feed and discharge pipelines, various types of water from domestic to cooling tower water, and
tomato sauces and juice. A non-invasive doppler flow meter, capable of measuring flow without cutting into the plumbing, was
important for the application.
One of the Del Monte applications required the Doppler flow meter to measure a 50% Potassium Hydroxide solution on a 2 inch, 304
stainless steel tube mounted outdoors. To properly install and calibrate a Doppler flow meter, the sound speed of the fluid
must be known. However, most fluid sound speeds are unknown, especially custom chemical blends and concentrations. Since
the 50% Potassium Hydroxide solution was not a standard fluid listed in the meter's menu, the Doppler flow meter was initially
configured for a "custom" fluid, with an estimated sound speed, and installed on the pipe. After the transducers were installed
on the pipe, the fluid's actual speed of sound was measured directly by the Doppler flow meter and displayed on the display screen. Then
the Doppler flow meter was re-configured for the correct sound speed and the transducers were re-positioned for high accuracy measurements.
The Sonic-Pro Doppler flow meter's ability to accurately test and continuously display the fluid's speed of sound eliminated the need
to send fluid samples to the lab and await speed-of-sound test results.
The portable FM500, Sonic-Pro clamp-on hybrid Doppler flow meter. The ability
to measure multiple pipe applications, various fluids, and pre-save multiple configurations for fast and easy installations made the
Sonic-Pro Doppler flow meters a clear choice.
