Compound water meter Woltman WPV-N-T
The WPV-N-T Woltman Turbo compound meter bulk water meter is a special design of the WPV

The WPV-N-T Turbo compound meter is a special design of the combination meter for recording extremely variable flows.

The difference between the WPV-N-T water meter and the standard compound meter is that the meter housing can remain in the pipeline for calibration replacement and only the calibratable measuring insert is replaced. The main meters, the secondary meters and the solenoid valve are mounted on a plate. Hence, calibration replacement can be performed simply, quickly and economically. The main meter is designed as a Woltman parallel and the secondary flow flows through a multi-jet measuring cartridge. Only one housing design is available, in which the secondary meter is mounted on the right-hand side.

As for the classic compound meter, the meter reading must be determined by adding the meter readings from the main meter and the secondary meter. Reed contact, optical and NAMUR induction encoders can be mounted on the main flow counter at any time without damaging the calibration seal. The secondary meter measuring cartridge is pulse system-ready as standard and can easily be fitted with a reed contact. Hence, integration into data transmission and management systems is greatly simplified.
