Dwyer Series DS IN-LINE Flow Sensors

Dwyer Series DS IN-LINE Flow Sensors

The Series DS In-Line Flow Sensors are two Series of averaging Pitot tubes for compatible gases and liquids that provide accurate and convenient flow rate sensing, for schedule 40 pipe.

The Series DS-300 Averaging Flow Sensors are designed to be inserted in the pipeline through a compression fitting and available for pipe sizes from 1 to 10" (2.5 to 25.4 cm). Accessories include adapters with 1/4" SAE 45° flared ends compatible with hoses supplied with the Model A-471 Portable Capsuhelic® Gage Kit.

The Series DS-400 Averaging Flow Sensors are designed for insertion lengths up to 24" (61 cm) and include a pair of 1/8" NPT x 1/4" SAE 45° flared adapters which are compatible with hoses used in the Model A-471 Portable Capsuhelic® Gage Kit. The supplied solid brass mounting adapter has a 3/4" dia. compression fitting to lock in required insertion length and a 3/4" male NPT thread for mounting in a threaded branch connection (not included).

1　　APPLICATION
  • Remediation
  • Natural, flare, flue, stack gas
  • Boiler feedwater
  • Cooling water
  • Superheated, saturated, or geothermal steam
  • Combustion or compressed air
  • Oil flow monitoring
2　　FEATURES
  • Multiple sensing point measurement and built-in averaging capability eliminates the need for “traversing” the flowing stream with single point velocity pressure measurement saving time
  • Extremely reliable, proven technology, Pitot tubes, have been used in flow measurement for years
  • All models include convenient and quick-acting quarter-turn ball valves to isolate the sensor 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 extra strong 3/4" dia. stainless steel to resist increased forces encountered at higher flow rates with both air and water
  • Economical flow indication when used with appropriate differential pressure gage
  • Rugged construction yields, non-clogging, stable design
