Manometers

Meriam Digital Pressure Manometers have many advantages in this age of technology because of their inherent accuracy and simplicity. Manometers are unique in being both pressure measurement instruments and standards for calibration of other instruments. The manometer is commonly used to measure pressures ranging from as high as 100 inches of 2.95 Red Fluid (10.65 PSI) to the lowest vacuums of space and assist with calibrating pressure. Manometers are available in varying designs depending upon application:

 

U-Tube Manometers
The U-tube manometer is the basic and most widely used style of manometer. The Meriam U-tube manometer is a versatile, economical instrument for the measurement of pressures, vacuums or differential pressures. Pressure measurements are accomplished by balancing a vertical head of indicating fluid with the pressure to be measured. There are no cams, gears, or levers to operate in the manometer. This allows the U-tube manometer to be recognized by NIST as a primary standard due to its inherent accuracy and simplicity of operation. Meriam U-tube manometers are constructed of a ridged cast aluminum frame, aluminum indicating scale and hand bent glass U-tube. Mounting holes are provided in the frame for mounting to a wall, column or other suitable structure.

 

Well Type Manometers
Well manometers are a direct reading device designed for process monitoring, general purpose production testing or laboratory measurement. Designed for a maximum line pressure of 250 PSI (500 PSI optional) these instruments may also be used for tank level, flow measurement and leak detection. Well manometers are constructed of aluminum channel, stainless steel end blocks and stainless steel manometer well. The 7/16 diameter glass tubing is yoke packed with viton gaskets at each end block and is supported at spaced intervals to prevent distortion. In most cases, the uncertainty of a manometer reading is +1/2 of the smallest scale graduation. This is due to the human eyes ability to interpolate between graduations.

 

Inclined Manometers
Inclined manometers provide greater readability by stretching a vertical differential along an inclined indicating column, giving more graduations per unit of vertical height. This effectively increases the instruments sensitivity and accuracy. Scales are typically graduated to the hundredth of an inch. The Model 40HEX Inclined manometer is individually calibrated and the angle of inclination is set relative to the instrument level mounted above the channel. The unit is also capable of operating with 350-PSI line pressure. The construction of the 40HEX35 is similar to the well type manometer described above. Additional inclined manometers are available depending on your requirements.

Orifice Plates & Flanges

Considered the most common primary element, Meriam’s concentric orifice plates are precision bored to exact dimensions with a sharp upstream edge to ensure accuracy. Pair this up with an orifice flange to provide a convenient, accurate method for installing orifice plates.

Gauges and Transmitters

Meriam offers a wide variety of mechanical and digital pressure gauges for process measurement and indication. Terrific accuracy specifications and little-to-no temperature effect set these instruments apart from the competition. Many of our digital gauge products have multiple output options to increase their versatility in today’s changing control schemes. Mechanical gauges have been the reliable standard in pressure measurement and still have their place in today’s industrial environment. They excel in areas where digital units cannot function, such as in very cold installations.
