Gauges - Marsh Bellofram
We offer pressure gauges, vital instruments that measure and indicate fluid or gas pressure within a system. These gauges are commonly employed in various industries, including manufacturing, oil and gas, automotiv...
Commercial pressure gauges cover HVAC, plumbing, fire protection and general building services. They're economical, easy to read and available in many standard ranges.
Commercial Gauge Options
- Dry and liquid-filled gauges – general service
- Brass internals – water, air and oil
- Common dial sizes – 2" to 4"
- Bottom and back connections – line or panel mounting
- Fire protection gauges – sprinkler system ratings
Choosing a Gauge
Select a range about twice normal operating pressure, and match connection size and dial type. Liquid-filled gauges handle vibration from pumps.
Centro supplies commercial gauges for HVAC, plumbing and building systems.

Industrial pressure gauges are built for the vibration, pulsation and rough handling found in plants, pump rooms and machinery. They give operators a dependable local reading of pressure in water, air, oil, steam and process lines.
Industrial Gauge Options
- Stainless steel cases – corrosion resistance and durability
- Liquid-filled gauges – dampen vibration and pulsation for steady readings
- Brass and stainless internals – match media compatibility
- Bottom and back connections – for line and panel mounting
- Dial sizes from 2" to 6" – readable at a distance
Selecting a Gauge
Choose a range so normal operating pressure sits in the middle of the dial, generally about twice the operating pressure. Use a liquid-filled gauge on pumps and compressors, and add a snubber for pressure spikes. Confirm the connection size and accuracy grade.
Centro carries industrial pressure gauges for plant, process and equipment applications.

Process pressure gauges are built for chemical, petrochemical, refining and power plant service. Heavy-duty cases, stainless wetted parts and high accuracy give dependable readings in demanding environments.
Process Gauge Features
- Solid-front safety cases – operator protection
- 316 stainless steel internals – corrosive media
- Liquid filling – vibration and pulsation damping
- Accuracy to 0.5% – precise readings
- 4.5" and 6" dials – easy reading
Choosing a Process Gauge
Choose range, accuracy, connection and materials suited to the process. Add diaphragm seals for corrosive, viscous or high-temperature media.
Centro supplies process gauges and accessories for plant instrumentation.

Test gauges, also called calibration gauges, provide high-accuracy readings for checking and calibrating other instruments. They're essential tools for maintenance and instrument technicians.
Test Gauge Options
- Analog test gauges – 0.25% accuracy with mirror dials
- Digital test gauges – high accuracy and data logging
- Wide range selections – vacuum to high pressure
- Calibration certificates – traceable documentation
Choosing a Test Gauge
Select accuracy at least four times better than the instruments you're testing. Choose range and connection to match. Handle and store test gauges carefully to protect accuracy.
Centro supplies test gauges for calibration and verification.
