40HEX35 Inclined Tube Manometer


For more information on purchasing this product please contact Meriam at 216.281.1100

Inclined Well Type Manometer for wall mounting is offered with scales from 20″ to 60″ long in differential ranges from 2″ to 20″. This economical and durable instrument fills the high sensitivity and accuracy requirements for low differential pressure ranges at operating pressures up to 350 PSI.

Inclined manometers provide greater readability by stretching a vertical differential along an inclined indicating column, giving more graduations per unit of vertical height and increasing the instrument sensitivity and accuracy. Inclined manometers frequently have scales graduated to hundredths of an inch. The Model 40HEX35 is often used to indicate differential across Meriam Laminar Flow Elements, Accutubes and Orifice Plates in gas flow applications.

The removable well is bolted to the back plate and connected to the glass tube through the lower end block. All pressure connections are 1/4″ female pipe thread. The scale with satin background, bold black figures, and precision graduations spans the full channel width behind the indicating tube. Scale and tube are protected by a transparent cover. Each Model 40HEX35 is individually calibrated and the angle of inclination is set relative to the instrument level mounted above the channel. The instrument finish is black textured urethane.
