The Meriam 10AA25 manometer is a versatile, economical instrument for the measurement of pressures, vacuums, or differential pressures.
The U-tube type manometer is a primary basic standard of pressure measurement. Pressure measurements are accomplished by balancing a vertical head of indicating fluid with the pressure to be measurement. As the are no cams, gears, or levers to operate the manometer; The readings obtained are always accurate.
The manometer has a rigid cast aluminum body frame protecting the glass U-tube on three sides. Mounting holes are provided in the frame for mounting to a wall, column or other suitable structure.
The clean-out head at the top of the instrument seals the indicating tube legs are also provides for the external pressure connections to the manometer. The manometer head fastens to the body by a single nut and is quickly and easily removed when necessary. This exclusive Meriam clean-out head feature permits cleaning and filling of the U-tube without disconnecting the piping to the manometer head. A 1/4" female pipe connection is provided out the left and right sides of the clean-out head can be furnished when specified. Manometer clean-out heads of cast iron, stainless steel or PVC are available for corrosive applications.
The manometer scale is located between the tube legs and overlaps the tube legs to a degree that eases reading at the meniscus position. The scale is readily adjustable for zero indicating fluid level.
The simple engineered method of supporting and sealing the U-tube in this manometer permits easy tube replacement in the field.
