Liquid-filled pressure gauges

If you have a dry gauge, don’t panic! Venting is strictly for liquid filled gauges. As discussed in When to Select a Liquid VS Dry Pressure Gauge, there are many advantages to a liquid gauge when used correctly in specific applications. When choosing the correct liquid filled gauge, there is another key detail to keep in the back of your mind. To ensure the longest possible life and accurate readings, pressure gauges that have soft-soldered pressure joints (General Equipment gauges with brass internals) should not be exposed to process or ambient temperatures over 120˚F. This is especially true of pressure gauges with liquid filled cases, due to the expansion of the case fill fluid. Liquid-filled pressure gauge can effectively suppress vibration, pulsation, and pressure peaks. Silicone oil and glycerin can also be used as lubricants and protect the precision parts of the instrument.

The glycerine in a liquid-filled gauge lessens the effect of vibrations, while also lubricating the internal parts, and preventing corrosion. Overall, a dry pressure gauges and liquid-filled pressure gauges can perform the same functions, however a liquid-filled pressure gauge will do these functions just a little bit better. Learn about the differences between liquid-filled pressure gauges and traditional pressure gauges. Liquid-filled pressure gauges are generally preferred for a better ROI and longer lifespan in extreme environments with temperature fluctuations or vibration.

Liquid-filled gauges are an excellent choice in environments where machinery generates significant vibrations or pulsations, such as mining, construction, The liquid-filled model 213.53 mechanical Bourdon tube pressure gauge is constructed with a case from stainless steel and wetted parts from copper alloy. WIKA manufactures and qualifies the pressure gauge in accordance with the standards EN 837-1 and ASME B40.100. High shock loads – strong vibrations – low ambient temperatures: three typical cases in which liquid-filled pressure gauges should be used. Compared to unfilled pressure gauges, pressure

Model 1555/1558/1559 liquid filled gauges have a crimped ring and dual scale psi/bar or kPa/psi dial as standard. The pressure gauge is suitable for environments with high vibration, pulsation, pressure spikes and condensation build up. Liquid filling protects the internals of the pressure gauge, and dampens the pointer to improve readability. WIKA’s liquid-filled pressure gauges are used in environments with shock and vibration loading. The filling liquid dampen pressure peaks, shocks, and vibrations. It protects the mechanics of the pressure gauge.

The use of liquid-filled, instead of dry, pressure gauges can help minimize these problems. With fewer problems and less downtime, liquid-filled pressure gauges are, in the long run, a more cost-effective solution.

Why is venting/cooling necessary? All mechanical liquid filled gauge cases are sealed (to keep the liquid in) so as they heat up pressure will build up in the case (approx 1psi for every 30-40F temperature change). This case pressure exerts a force on the mechanical movement and offsets the actual process pressure. These pressure gauges are available in both 2½“ or 4″ sizes, in panel mount and low mount configurations. The liquid fill minimizes the effect of these severe environments, protects the gauge internals, and provides continuous lubrication So you’ve figured out what size dial and connection you need on the gauge for your application. You even know your preference on wetted materials. But what about having the gauge dry vs. liquid filled? What are the benefits to a liquid filled gauge? Are there any negatives? Believe it or not, determining this feature Why Are Pressure Gauges Liquid Filled? Read More »

Winters is a leading global manufacturer of pressure gauges, pressure transmitters, pressure switches, diaphragm seals, thermometers & digital instruments.

Liquid filled pressure gauges provide users with a number of advantages in certain measurement applications.The gauge design is NEMA 4X / IP67 compliant to increase durability. Liquid filling also provides greater protection of the gauge internals from corrosive atmospheres.

Liquid-filled pressure gauges are widely used in applications involving high pulse pressure and shock loads. The filling fluid can suppress the vibrations that occur and remove the load on the mechanical components of the pressure gauge, so this pressure measuring instrument is often called a shock-resistant pressure gauge.

Best fluid to refill this pressure gauge? Mineral oil? Is this a normal amount to be missing or should I top it off?

For gauges with pressure ranges of 60 psi or less, the pointer must be pre-adjusted before liquid fill-ing. To adjust the pointer, use the adjustment screw on the pointer as described in Section V, Item 2 (Pointer Assembly and Adjust-ment). All liquid filled pressure gauges can be filled with glycerin, silicone, or mineral oil, and are NEMA 4X/IP66 or IP67 compliant. Click here for a comparison of our pressure gauges.

It helps increase the life of the gauges by dampening as well as lubricating the mechanical parts of a pressure gauge Negatives of a Liquid Filled Gauge Discoloration (darkening or yellowing) of glycerin over time due to exposure of UV rays or extreme temperature changes Standard Glycerin is really only good down to 20 degrees In this blog, we will dive into how to properly vent a liquid filled gauge and how to determine which style of fill plug best fits your operation.

The higher the liquid viscosity, the greater its dampening capacity. The reason for this is that dampening changes in proportion to the temperature-dependent viscosity of the filling liquid. The suitable degree of dampening depends on the operating requirements the gauge must meet, such as pointer response time, pressure extremes, vibration, and changes in pressure. WIKA can When it comes to choosing a pressure gauge, the decision might seem simple. Liquid filled or dry.
