These 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.

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.

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

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.

Meriam manufactures the widest range of Averaging Pitot Tubes for gases, liquids and steam with bi-directional flow capability. Under the Accutube brand name, there are four standard models; Inline, Insertion, Flanged and Wet Tap which can provide a flow solution for your toughest applications.

Meriam offers a wide variety of mechanical and digital pressure gauges for process measurement and indication. Excellent 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.
