Insertion Ultrasonic Flowmeter

Insertion flowmeters uses hot-tap insertion transducer for more accurate liquid flow measurement. Insetion ultrasonic flow meter has a higher accuracy and lower cost.And have no moving parts.

                            Insertion(Hot-tap) Liquid Ultrasonic Flowmeter




The insertion flowmeter is designed for pipe larger than 3” (DN80mm). For smaller pipe, our spool-piece model, flow cell type flow meter, might be a better choice. When pipe size becomes smaller, the cost of a spool-piece transducer comes down.

Comparing with clamp-on flowmeters,insertion flowmeters have better accuracy, and comparing with inline flowmeter, insertion flowmeters have lower cost and less maintenance.
Insertion liquid ultrasonic flow meter employs a pair of insertion-type ultrasonic transducers to measure the flow by inserting the transducers into the pipe wall. Comparing with clamp-on flowmeter, the biggest advantages of our wetted-type flowmeter are its long-term stability, better signal quality and less installation uncertainty. The last two features can also be translated into higher accuracy.
The Insertion type flow meter is ideal for flow surveys and closed-pipe applications, such as normal water flow measurement (hot/chill water, city water, sea water), sewage and sludge measurement, and measurements of oil (crude/diesel/fuel), chemicals (alcohol, acids, etc.), beverage, and many other liquids.
