Meriam 40HEX35 Inclined Tube Manometer

Inclined Tube Manometer Well Type

• SWP = 350 PSIG
• Better resolution for 2.00" wc to 20.00" wc
• Several scale units available
• Scale lengths of 20" to 60" for improved readability

The Meriam 40HEX35-WM inclined manometer has an aluminum channel with stainless steel end blocks into which a large bore, borosilicate glass tube is securely yoke packed with viton gaskets. The remove-able well is bolted to the back plate and connected to the glass tube through the lower end block. All pressure connections are ¼" female pipe thread.

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.
