Application

What kind of pipe material enables ultrasonic measurement?
We have had numerous experiences with measurements through steel, stainless steel, cast iron,
ductile iron, and resins.
  1. Although we have measured through RC steel pipes, transmission of acoustic signals is difficult and this type of pipe material is not conducive to ultrasonic measurement.
  2. Measurement through pipes of asbestos material is possible on rare occasions, but for all practical purposes, measurement is not possible with this material.
  3. Hume pipes cannot be measured with sensors mounted on the outside of the pipe. Special measurement methods incorporating sensors on the inside of the pipe are employed for this type of application.
  4. The ultrasonic might not be propagated easily with PVC lining steel pipe. Refer to 3.3.
  5. The ultrasonic might not be propagated easily into the Zinc-coated-pipe.
What are the minimum and maximum measurable pipe sizes?
Measurable diameters are from DN13mm to DN5000mm.
Is pipe lining a problem?
Mortar, epoxy and other common linings on the inside of pipes do not affect measurement. In
cases where the outsides of pipes are wound with jute or similar material, remove this material at
the location where the transducers are to be positioned.
Regarding to PVC lining steel pipe, this type of pipe may contain air layer between metal part and
PVC lining partially due to its manufacturing way.
In such case, it could be find better point for ultrasonic on the same circumferences or another
part.
