Product Description

The Dwyer PAFS-1003 is an average flow probe with four detection points for fluid measurement applications. Built from ABS/polycarbonate material rated UL94-5V, it accommodates 6 mm ID tubing and operates from 4 to 49°C. Suitable for process monitoring and flow verification systems.

Frequently Asked Questions

What is the Dwyer PAFS-1003 average flow probe used for?

The Dwyer PAFS-1003 average flow probe is used for measuring differential pressure in HVAC zone control, variable-air-volume terminal units, and ventilation duct systems. It detects total pressure on the H port and static pressure on the L port, providing dynamic pressure readings for process monitoring and flow verification.

What are the specifications of the Dwyer PAFS-1003?

The Dwyer PAFS-1003 has four detection points, a length of 13.73 cm, and is made of ABS/polycarbonate rated UL94-5V. It accommodates 6 mm ID, 10 mm OD tubing, operates from 4 to 49 °C, and stores from -40 to +60 °C. Weight is 28 g. Service is for air and compatible gases.

Where to buy the Dwyer PAFS-1003 in Singapore?

3G Electric supplies the Dwyer PAFS-1003 average flow probe to Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time. As a sourcing partner, we provide technical support for HVAC and process applications.

How to install the Dwyer PAFS-1003 average flow probe?

Install the Dwyer PAFS-1003 by mounting it with the integral flange and foam gasket. Connect 6 mm ID, 10 mm OD tubing to the push-on connections. Ensure the H port faces total pressure and the L port faces static pressure. Follow Dwyer's guidelines for duct insertion and sealing to avoid leaks.
