Flowmeters

Series DR4 Glass Flowmeters offer a simplified solution to the problem of fluid flow indication at higher capacity levels. Flowmeters have a direct reading scale for air or water and are designed to withstand even the harshest industrial applications. Permanently fused ceramic scale has integral float guides for optimum float performance. Reflective plastic background and 1.5 X magnification lens reduces eye fatigue and allows for more accurate readings. Units include a safety blow-out back panel for additional protection.

In-Line Flow Sensors are averaging Pitot tubes that provide accurate and convenient flow rate sensing for schedule 40 pipe. When purchased with a Dwyer Capsuhelic differential pressure gage of appropriate range, the result is a flow indicating system delivered off the shelf at an economical price. Pitot tubes have been used in flow measurement for years. Conventional Pitot tubes sense velocity pressure at only one point in the flowing stream. Therefore, a series of measurements must be taken across the stream to obtain a meaningful average flow rate. The Dwyer flow sensor eliminates the need for traversing the flowing stream because of its multiple sensing points and built-in averaging capability. Dwyer Series DS-300 flow sensors are designed to be inserted in the pipeline through a compression fitting. They are furnished with instrument shut-off valves on both pressure connections. Valves are fitted with 1/8 female NPT connections. Accessories include adapters with 1/4 SAE 45° flared ends compatible with hoses supplied with the Model A-471 Portable Capsuhelic Gage Kit. Standard valves are 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. Series DS-300 flow sensors are available for pipe sizes from 1 to 10. 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. This extra strength also allows them to be made in longer insertion lengths up to 24 inches (61 cm). All models include convenient and quick-acting quarter-turn ball valves to isolate the sensor for zeroing. Process connections to the valve assembly are 1/8 female NPT. A pair of 1/8 NPT x 1/4 SAE 45° flared adapters are included, compatible with hoses used in the Model A-471 Portable Capsuhelic Gage Kit. 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).

Series GFM Gas Mass Flow Meters combine a straight tube sensor with a restrictor flow element to provide high accuracy and repeatability. Flow rates are virtually unaffected by temperature and pressure variations. Actual gas flow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCD readout. Units can be used with Series GFT Flow Totalizer for applications requiring totalization. Series GFM includes a NIST traceable certificate. aluminum Gas mass flow meter range 0-10 mL/m Specified flow range is for an equivalent flow of nitrogen at 70°F (21°C) @ 760 mm Hg 1/4 compression fitting
