Pitot Tube Flow Meter is a reliable and efficient solution for measuring air and gas flow in wastewater treatment plants (WWTPs) (ie on the discharge line of roots blowers). By providing accurate airflow measurement, it enables operators to verify aeration performance, detect blower degradation, and optimize energy consumption in the biological treatment process.
The flow meter features a 1/2″ insertion probe with a compact sensor design, making it suitable for pipe sizes ranging from DN25 to DN300. Insertion-type allows for quick installation with minimal pipe modification, reducing maintenance downtime and operational disruption.
PTF520 pitot tube flow meter is equipped with Bluetooth communication configuration. With the Comate Bluetooth App, plant operators can conveniently view real-time data, perform diagnostics, and adjust instrument settings directly from a mobile device. This is particularly valuable for instruments installed in elevated, confined, or otherwise difficult-to-access locations, improving both maintenance efficiency and personnel safety.
It is essential to ensure the optimal operation of the flow meter to maximise the measurement performance. Pitot tube flow meter allows high performance flow condition in an installation with longer meter run lengths. It is also recommended to eliminate upstream fitting for optimal performance. Bluetooth communication function on the flow meter ease the monitoring and installation at difficult-to-access locations. Along with the Comate Bluetooth APP, it allows plant operators to monitor, diagnose and configure the flow meter from their mobile device during maintenance.
Comate PTF600 Heavy Duty Pitot Tube Flow Meter uses the differential pressure measurement principle, suitable for wet and dry air measurement. The DP transmitter turndown ratio is 33:1, offering a better stability and wider measurement range. The unique water-proof design eliminates issues caused by water condensation in the capillary. It is less affected by the water contents in the compressed air.

Comate PTF520 Pitot Tube Flow Meter uses the differential measurement principle, suitable for compressed air applications. The 1/2″ insertion connection probe and compact designed sensor can be used on pipes from DN25 to DN300. In high pressure applications, it can be installed or removed without stopping the processline, as the pipe is thinner, field engineers will be able to insert the meter to pipe very easily.
