Reinforced pointer stops, a heavy-duty movement mount, and glycerin damping keep readings legible and the instrument intact during ground shaking, blasts, and heavy mechanical shock, protecting the pressure data building and plant operators rely on when it matters most.

Precision instrumentation engineered for seismic proof glycerin filled manometer applications
The Seismic Proof Glycerin Filled Manometer is engineered for installations where the ground itself moves: fire-protection and sprinkler systems in earthquake-prone regions, nuclear and power plant auxiliary systems, mining and tunneling equipment, and heavy rail or crane structures. In these environments the instrument must survive short, violent acceleration events and keep giving a meaningful reading immediately afterwards, not merely stay attached to the pipe.
The movement is mounted on a reinforced frame with a stiffened Bourdon tube support, and the pointer is protected by a buffer stop that prevents the needle from whipping past zero or striking the dial glass during a shock. Glycerin fill adds viscous damping that absorbs the energy of the event and cushions the gear train, so pivots and teeth are not hammered by sudden acceleration. The fill also prevents the pointer from bouncing wildly during ongoing low-frequency shaking.
Assembly and shock qualification take place in our 100,000-level clean workshop and adjoining test area, where sample units are subjected to drop and impact tests, and reference readings are checked before and after each event to confirm the zero and span did not shift. Test data and fill batches are stored in our Advanced MES digital tracking system against each serial number to support seismic qualification files and project handover documents.
Mounting details matter as much as the gauge: a rigid stainless steel case, a reinforced mounting flange or bracket, and a flexible or braided connection are offered so the gauge is not cantilevered from a stiff pipe that could transmit bending loads into the instrument during a seismic event. These options let engineers integrate the manometer into project-specific seismic support designs.
