TESCOM™ Anderson Greenwood Instrumentation Series M20 Differential Pressure Manifold

Enables external transmitter zeroing via single handle.;Lockable handle may be screw locked in any position or padlocked in OFF position, for personnel safety.;AG Mount direct pipe stand mounting enables early installation without transmitter and easy instrument removal for maintenance.;Correct fixed valve sequence ensures accurate transmitter pressurization and zeroing. Port sequencing always admits high side pressure to transmitter first, preventing possible zero shift from reverse over-ranging.;Safe venting of manifold and instrument cavities protects personnel during maintenance.;Seal fluids cannot be lost when manipulating to ZERO, RUN or OFF, providing major savings in down time and seal fluids.;Foolproof manual configuration prevents incorrect transmitter over-ranging and transmitter burn-out due to equalizer valve being left open for flow.
