What is a Dwyer gauge?
Page Contents
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.
Who owns Dwyer Instruments?
Arcline Investment Management
MICHIGAN CITY – Michigan City-based Dwyer Instruments has been acquired by Arcline Investment Management of San Francisco. Financial terms of the deal were not disclosed. Dwyer, which was founded in 1931, designs and manufactures sensor and instrumentation solutions for HVAC and building automation markets.
What is the difference between a Photohelic and Magnehelic gauges?
Magnehelic® Pressure Gauges are used to measure the differential pressure between the “clean” gas side and the “dirty” gas side of the baghouse. The Photohelic gauge allows for “on-demand” cleaning which not only saves you money through decreased compressed air usage, but also extends the life of your filters.
How does a digital manometer work?
Rather than using fluids, digital manometers do the same job but use a pressure transducer. An elastic portion of the transducer detects pressure levels and converts this energy into an electronic signal, producing a number instantaneously on a digital display.

Why mercury is used in manometer?
Mercury is a useful material to use in a manometer because of its high density. This means that a much shorter column is needed compared to water. For instance, the pressure represented by a column of 100 mm of water is just under 7.4 mm of mercury (mmHg).
What is differential manometer?
Differential manometers are the devices used for measuring the difference of pressure between two points in the same pipe or in two different pipes. • A differential manometer of a U-tube are connected to the points, whose difference of pressure is to be measured.
Are digital manometers accurate?
Digital Manometers and Their Many Uses The manufacturer claims 0.1% accuracy at 100 inches of water. You set up a test using a deadweight tester and a water manometer.
What is a digital manometer?
A hand-held pressure measuring device that uses a transducer to covert pressure to a corresponding voltage. A digital manometer typically indicates pressure measurements using a digital display.
What does a manometer measure?
The most basic manometers measure gas/liquid pressure against atmospheric pressure
Digital manometers are devices that are capable of measuring pressure and its variations across two points that are a part of the same system-this is known as differential pressure. Differential pressure is of great importance to weather forecasters, among others.
What is differential pressure meter?
A differential pressure meter is used to measure differential pressure in pneumatic, compressor and pump installations, valves, tanks and heating, ventilation and air conditioning (HVAC) systems.
What is a manometer gauge?
A manometer gauge is an extremely basic but very effective device which is used to measure pressure. In the majority of cases this will relate to a gauge which consists of a U-shaped glass tube which is filled with mercury or some other liquid. Traditionally one end of the manometer tube is left open,…
