Made in Japan
Manufacturer: Nippon Flow Cell
Model: PF

This flow meter actively manages the flow in air conditioning systems, measuring the flow of chilled and hot water used in building air conditioning systems. Since it utilizes a Pitot tube, it is easy to install and has almost no pressure loss.

Features

• Accurate measurement with a double scale.
• Red for Hot water (60°C), Blue for Cold water (7°C).
• The specially structured Pitot tube enables high-accuracy measurements, even with minimal straight pipe lengths of 5D upstream and 3D downstream from the installation point.
• Maintenance and inspection of the indicator section can be done without stopping the flow.
• Can be easily installed on existing piping.
• Detachable indicators can be used on multiple piping systems.
