DS-300-3 | Flow sensor | 3" pipe size. | Dwyer Instruments

3" In-line Flow Sensor (DS-300-3) by Dwyer Instruments Dwyer Instruments DS-300-3 is a 3-inch In-line Flow Sensor designed to provide accurate and real-time flow measurement in industrial applications. Made of durable stainless steel and featuring a solid-state thermal dispersion sensing element, this sensor offers reliable performance in harsh environments. The DS-300-3 sensor operates on the principle of thermal dispersion, where a heated element is placed in the fluid stream. The rate of heat dissipation from the element is directly proportional to the fluid velocity. This allows for precise flow measurement, independent of fluid properties such as density or viscosity. With a wide flow range and high accuracy, this sensor is ideal for measuring the flow of gases and liquids in pipes or ducts. It features a 4-20 mA output signal, allowing for easy integration with control systems or data acquisition devices. Applications: - Flow measurement in HVAC systems - Industrial process control - Monitoring and control of air and gas flow - Leak detection in pipelines - Combustion control Specifications: - Flow Range: 0.5 to 1000 SFPM - Accuracy: ±1% of reading - Temperature Range: -40 to 140°F - Pressure Range: 0 to 100 PSI - Output Signal: 4-20 mA Shop now on our HVAC supply store and take advantage of the best prices and fast shipping for all your industrial needs!

Series DS In-Line Flow Sensors

• Multiple sensing point measurement and built-in averaging capability eliminatesthe need for “traversing” the flowing stream with single point velocity pressuremeasurement saving time
• Extremely reliable, proven technology, Pitot tubes, have been used in flowmeasurement for years
• All models include convenient and quick-acting quarter-turn ball valves to isolate thesensor for zeroing with 1/8" female NPT valve assembly process connections.
• Furnished with instrument shut-off valves on both pressure connections with 1/8"female NPT connections rated at 200 psig (13.7 bar) and 200°F (93.3°C)
• Where valves are not required, they can be omitted at reduced cost
• The Series DS-400 Averaging Flow Sensors are quality constructed from extrastrong 3/4" dia. stainless steel to resist increased forces encountered at higher flowrates with both air and water
• Economical flow indication when used with appropriate differential pressure gage
• Rugged construction yields, non-clogging, stable design
