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.
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.
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.
