Oil & Gas
From the wellhead to the refinery, oil and gas plants run at high pressure with corrosive, sour and abrasive media. Gauges have to stay readable and safe in all of it.
Typical applications
- Upstream: wellheads, Christmas trees, separators and water injection
- Midstream: pipelines, compressor stations and storage terminals
- Downstream: refining units, heaters and product lines
Challenges
- Pressures up to several hundred or thousand bar on wellheads and injection lines
- Sour gas (H₂S) and hydrogen that can permeate thin diaphragms
- Vibration and pulsation from compressors and pumps
- Seawater and chlorides on offshore and coastal sites
Recommended products
High-pressure gaugesWellheads, injection and test lines, up to 3000 bar.
Sealed diaphragm gaugesSour or hydrogen service, with a gold-plated or Monel 400 diaphragm.
Glycerine-filled gaugesCompressor and pump discharge, where the needle must stay steady.
Gauge accessoriesNeedle valves, manifolds and snubbers rated for the line pressure.Materials and options

Chemical & Petrochemical
Reactors, columns and transfer lines handle acids, alkalis, solvents and polymers. The wetted parts must resist the medium, and the gauge must not block.
Typical applications
- Reactors and agitated vessels
- Distillation columns and heat exchangers
- Transfer, dosing and loading lines
- Polymer, resin and solvent processes
Challenges
- Strong acids, alkalis and chlorides that attack standard steels
- Viscous, crystallising or polymerising media that clog a Bourdon tube
- High process temperatures
- Pressure drop across filters and strainers
Recommended products

Pharmaceutical & Life Sciences
Process lines are cleaned and sterilised often, and every instrument must be hygienic, easy to clean and backed by documents for validation.
Typical applications

Power & Energy
Boilers, turbines and their utilities run on steam, oil and cooling water. Gauges must cope with heat, pressure surges and constant vibration.
Typical applications

- Turbines, lube oil and fuel oil systems
- Cooling water and condensate
- Compressed air and auxiliary systems
Challenges

Water & Wastewater
Pumping stations, treatment plants and desalination units need gauges that read steadily against pulsation and survive sludge, chemicals and seawater.
Typical applications
- Pumping stations and distribution
- Filtration, RO and desalination
- Sludge handling and aeration
- Chemical dosing (chlorine, coagulants)
Challenges
- Pulsation from pumps
- Sludge and solids that block the connection
- Chlorinated and corrosive dosing chemicals
- Seawater and brine in desalination

Steel & Metals
Presses, rolling mills and furnaces combine very high hydraulic pressure with heat, dust and heavy vibration.
Typical applications

- Rolling mills and continuous casting
- Furnaces, burners and combustion air
- Cooling water and industrial gases
Challenges
- Very high hydraulic pressure and pressure spikes
- Heavy vibration and shock
- Heat and dust around the gauge
- Low draft pressures on furnaces
