Choosing the Right Gauge

Glycerine-filled pressure gauges are useful where vibration or pressure pulsation causes the pointer of a dry instrument to fluctuate. The liquid filling dampens movement and makes the indication easier to read.

Choose the pressure range around the normal operating point, allowing appropriate headroom for expected variation. Filling does not increase the gauge's pressure rating or overload capability.

Material compatibility remains essential. Check the wetted parts, seals and operating temperature against the gas or liquid being measured, then confirm dial size, thread form and entry position.

For stainless steel construction, compare the relevant filled models within the all stainless steel pressure gauge range. For stable installations, browse dry industrial gauges; pressure snubbers can help manage rapid pressure changes at the instrument.

Vibration and Pressure Pulsation

Mechanical vibration reaches a gauge through its mounting, while pressure pulsation reaches it through the process connection. Both can cause pointer movement, but identifying the source helps determine the appropriate response.

Glycerine filling dampens movement and improves readability; it should not be treated as protection against every pressure spike or an unsuitable pressure range.

Persistent surges may require a snubber or a change to the installation. Always check pressure, temperature and material compatibility independently of the case filling.

Steadier Indication

Liquid filling dampens pointer flutter, making the reading easier to follow on vibrating or pulsating equipment.

Material Choices

Choose the wetted materials for the process medium independently of whether the case is filled.

Five Dial Sizes

Compare 40, 50, 63, 100 and 160 mm dials, with bottom- and back-entry options across the range.

Applications

Designed for local indication on pumps, compressors, hydraulic equipment and machinery where vibration or pulsation affects readability.

Hydraulic power units

Read pressure on equipment where operating vibration affects the dial.

Pumps and compressors

Improve readability where pulsation makes a dry pointer fluctuate.

Mobile machinery

Select a filled gauge with a specification suited to the machine's operating conditions.

How to Choose

Identify the source of pointer movement, select a suitable range, confirm the wetted materials and match the dial size and connection.

Identify the disturbance

Establish whether vibration, pulsation or a pressure surge is affecting the instrument.

Choose a suitable scale

Cover working pressure and expected peaks without continuous operation near full scale.

Check materials and temperature

Confirm wetted-part, seal and fill suitability for the duty.

Select the physical fit

Match dial size, connection thread and entry position.

Frequently asked questions

Practical answers to help with selection and replacement.

What is the glycerine for?

It fills the case around the mechanism to damp movement. It is separate from the process medium.

Does filling make a gauge more accurate?

It can make the pointer easier to read, but it does not change the stated accuracy.

Is every filled gauge suitable for hydraulic oil?

Check the wetted materials, seals, pressure and temperature against the particular fluid and system.

Do I still need a snubber?

Some installations benefit from one. It depends on the pressure fluctuations, medium and response time required.
