2000 magnehelicSeries 2000 Magnehelic® Differential Pressure Gage

The Magnehelic® gage is highly acccurate –guaranteed within 2% of full scale, with a wide choice of 81 models available to suit your needs precisely. Using Dwyer’s simple, frictionless Magnehelic® gage movement, it quickly indicates low air or non-corrosive gas pressures–either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems.

4000 capsuhelicSeries 4000 Capsuhelic® Differential Pressure Gage

The Capsuhelic® gage is designed to give fast, accurate indication of differential pressures. Using the basic design of Dwyer’s time-proven Magnehelic® gage, the Capsuhelic® gage contains a simple, frictionless movement that permits full scale readings as low as 0.5 inch water column. The pressure being measured is held within a capsule which is an integral part of the gage. This containment of the pressure permits the use of the gage on system pressures of up to 500 psig, even when differentials to be read are less than 0.1 inch w.c.

rmv flowmeterSeries RMV Rate-Master® Dial-Type Flowmeter

Series RMV Rate-Master® Flowmeters measure higher water flow rates with ±2% of full scale accuracy at affordable prices. Rugged forged brass housing is standard on all models for great compatibility and the strength to withstand system pressures to 1000 psig (68.9 bar). Unlike glass tube rotameters, these units won’t shatter and they work fine with even dark and/or opaque liquids. Stocked models are fitted with 1″ female NPT inlet and outlet; 3/4″ and 1/2″ sizes are also available. Install in line, supported by piping or flush panel mount with complete hardware package included.

rotometersSeries VF Rotometer

The Visi–Float® flowmeter bodies are cut and precision machined from solid, clear acrylic plastic blocks. The front scale location and white background provides excellent visibility. The direct reading scales are hot stamped into the plastic and will not wear off. Mid-range calibration is established with a master flowmeter. Accuracy is ±5% of full scale for VFA models, ±3% for VFB. Scales average 2″ long on the VFA models, 4″ long on VFB. Available with either brass or stainless steel inlet and outlet connections tapped for 1/8″ NPT thread. VFB models 85 and 86 have either 1/4″ back or 3/8″ end connections. Precision metering valves in brass or stainless steel are available for most VFA and VFB models.

v4 flotectSeries V4 FLOTECT® Vane Operated Flow Switch

Rugged and reliable the Series V4 Flotect® flow switch operates automatically to protect equipment and pipeline systems against damage from reduction or loss of flow. The V4 is time tested being installed in thousands of pipelines and processing plants around the world. A unique magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Instead, a free-swinging vane attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm.

v6 flow switchSeries V6 FLOTECT® Mini-Size Flow Switch

The Series V6 Flotect® Flow Switch is engineered to specifically monitor liquid, gas, or airflows. Operation is simple and dependable with no mechanical linkage as the flow switch is magnetically actuated. The lower body holds the flow vane and one magnet, which controls the switch actuating magnet in the separate upper housing. In most applications the switch is normally off with the pipeline flow forcing the vane against the vane spring. As the flow decreases the vane spring pushes back the vane, actuating the switch to signal an alarm or shutdown. Tees are available for installation in pipelines from 1/2″ to 2″, with bushings added the unit is easily adapted to 1/4″ and 3/8″ piping.
