The brand's catalogue comprises differential pressure gauges, switches and transmitters; flow and backflow kits and accessories, such as diaphragm seals, manifolds and pressure limiting valves. Mid-West differential pressure gauges measure the difference between two points in a system and display the resulting pressure change on the gauge dial. They come with a glass-reinforced thermoplastic dial of 2.5 / 4.5 inches, an operating temperature range of -40 to 200 F and a differential pressure range of 0 - 100 psid. Raptor Supplies also offers a wide range of differential pressure gauges for measuring pressure drops across filters, strainers, separators, valves, pumps and chillers.

Differential Pressure GaugesWeather-resistant differential pressure gauges with an accuracy of + / - 3%; ideal for measuring the pressure drop across filters, strainers, separators, valves, pumps and chillers. Tri-color differential pressure indicators also available (319 Products)
Backflow Preventer Test KitsIncludes 5-valve backflow test kits with a 90-micron filter to minimise plugging and brass needle valves (with replaceable valve seats). Provide differential pressure up to 15 psi at +/- 0.2 psid accuracy. Connecting adapters, replacement hoses, bleed-off valves and filters also available (14 Products)
Mid-west Instrument MPNs cross individual references to the equivalent Dwyer model numbers for differential pressure gauges. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Mid-West products available.
Mid-West thermometers and hydrometers have a small footprint and require compact packaging. Thus, these units can be delivered in a short period through courier shipment or air freight.

These gauges allow process fluid to migrate across the piston from the high to the low side. They feature a precision ground floating piston / magnet in a diamond reamed bore against a calibrated spring to sense the pressure difference (up to an accuracy of +/-5 percent). A rotary pointer magnet on ...
This gauge comes with a tri-colour dial (CLEAN / CHANGE / DIRTY) to quickly identify pressure drops across elements. It senses the differential pressure with the help of a flexible elastomer diaphragm and a calibrated spring while maintaining a total separation between high and low-pressure signals.
Model 115 and 116 comprise a two-piece body, bellows sensing element & over pressure assembly; a torque tube assembly, a spring and gauge front assembly. These gauges have rugged construction and a waterproof design for working well with LOX & CO2, Nitrogen, Ammonia, Hydrogen and Argon gases. They c...
The backflow test kit is specifically designed for testing all reduced pressure principles, pressure vacuum / spill resistant breakers and double-check valve backflow prevention assemblies with an accuracy of +/-2 psid. This testing kit features soft-seated brass needle valves, a maximum operating temperature of 150 degrees F, an engineered plastic...
The differential pressure gauge must be calibrated regularly (or on a prescribed date) to ensure the testing device can provide accurate readings.
The needle valves restrict or allow flow by using a slender needle-shaped plunger. They regulate the flow of liquid or gas in metering applications.
Mid-West differential pressure switches are supplied with reed switches or relays to initiate an alarm, activate the equipment or shut off the system.
