The Dwyer Instruments DS-400-24 is an averaging flow sensor designed for accurate and convenient flow rate sensing in schedule 40 pipe. This model features a 24-inch probe length and is constructed from extra strong 3/4-inch diameter stainless steel to withstand higher flow rates and longer insertion lengths. When paired with a Dwyer Capsuhelic differential pressure gage, it forms a complete flow indicating system delivered off the shelf at an economical price.
Key Features & Highlights
- Accurate Averaging: Multiple sensing points provide a true average flow rate, eliminating the need for traversing the stream.
- Durable Construction: Extra strong 3/4-inch stainless steel probe resists forces at high flow rates with air and water.
- Long Probe Length: 24-inch insertion length accommodates larger pipe sizes and installation requirements.
- Quick-Acting Ball Valves: Quarter-turn ball valves allow easy isolation for zeroing and maintenance.
- Versatile Connections: Includes 1/8 NPT x 1/4 SAE 45° flared adapters compatible with Dwyer Model A-471 Portable Capsuhelic Gage Kit hoses.
- Easy Installation: Solid brass mounting adapter with 3/4-inch compression fitting locks insertion length and 3/4-inch male NPT thread for branch connection.
Applications
The DS-400-24 is ideal for HVAC, industrial process, and environmental monitoring applications where accurate air or water flow measurement is critical. It is suitable for use in pipe sizes from 1 to 10 inches and can be used with a variety of Dwyer differential pressure instruments.
