Product Description

The Dwyer PAFS-1009 is an average flow probe for HVAC and fluid systems, featuring 10 detection points across 6 mm ID tubing for enhanced measurement accuracy. Constructed from ABS/polycarbonate (UL94-5V), it operates from 4 to 49°C and suits applications requiring distributed flow sensing.

Frequently Asked Questions

What is the Dwyer PAFS-1009 average flow probe used for?

The Dwyer PAFS-1009 average flow probe is used for measuring differential pressure in HVAC systems, specifically in variable-air-volume terminal units and main or branch ducts. It detects total pressure on the H port and static pressure on the L port, with the difference representing dynamic pressure for airflow measurement.

What are the specifications of the Dwyer PAFS-1009?

The Dwyer PAFS-1009 has 10 detection points, 6 mm ID and 10 mm OD tubing, and is made of ABS/polycarbonate (UL94-5V). It operates from 4 to 49°C and stores from -40 to +60°C. The probe length is 49.29 cm, weight is 28 g, and it includes an integral mounting flange with foam gasket.

Where to buy the Dwyer PAFS-1009 in Singapore?

You can source the Dwyer PAFS-1009 average flow probe through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this Dwyer measurement probe.

How to install the Dwyer PAFS-1009 average flow probe?

Install the Dwyer PAFS-1009 by mounting it through a duct or terminal unit using the integral flange and foam gasket. Connect the H port to total pressure and L port to static pressure using 3/8-inch (9.53 mm OD) poly tubing. Ensure the probe is positioned perpendicular to airflow for accurate differential pressure sensing.
