Dwyer

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). Probe Length 20 less valves

Customers tell us that this is the best pressure switch made. The Mercoid D Series is one of the worlds broadest lines of pressure switches. Whatever your application might be, it is most probable it can be fully satisfied with a D Series pressure switch. The D Series has extremely high sensitivity and great repeatability. The DA Models are equipped with two external adjustments, one for setting high pressure operating point, the other for setting low pressure operating point. Deadband, the difference between high and low set points, is adjustable over the full scale. The DS Models are equipped with a single external adjustment for setting operating point only. The deadband is fixed at a factory setting and cannot be altered in the field. For switches choose between the snap action switch, hermetically sealed snap action switch and hermetically sealed mercury switch. Visible calibrated dial On/off indication (except hermetically sealed snap switch models) Adjustable or fixed deadband SPDT snap-action, hermetically sealed snap action or hermetically sealed mercury switch External switch setpoint adjustments Minimum deadband is obtainable at any point in the range Pressure Ranges of full vacuum to 8000 psig UL listed, CSA approved. Many models FM approved General purpose, weatherproof or explosion-proof enclosures Snap Switch, Hermetically Sealed Brass Standard with Bottom Connection 9-64, SPDT 0.125 15 psig
