Glycerine filled manometer can be applied to more ranges

  •   Generally, Glycerine filled manometer is better than a dry pressure gauge for two reasons: performance and ROI. Liquid-filled meters are filled with liquid, usually glycerin or silicone oil, and are designed to achieve optimal performance under undesirable conditions. Glycerine-filled manometers can work in harsh environments, but from a long-term perspective, they are also more economical. High heat, pulsation, or vibration can cause damage to the instrument, but the liquid-filled meters of Vacuum pressure gauge Manufacturers can withstand these harsh conditions.

      Liquid filling and traditional gauges

      The main cause of instrument failure is vibration. In traditional dry pressure gauges, the precision chain links, pivots, and pinions are easily damaged by vibrations, resulting in unstable performance. In a liquid-filled meter, the fluid filling effectively suppresses system pulsation, making the meter pointer easier to read.

      Similarly, humidity and humidity can cause problems for dry pressure gauges. Condensation can make the meter difficult to read, or in some cases can cause malfunctions due to icing. However, liquid-filled meters will be sealed to prevent internal condensation, and by preventing moisture from entering the system, the meter can be protected from movement under icing conditions.

      The choice of filling fluid depends on the specific application, but glycerin is generally used for room temperature applications, while silicone oil is generally used for extreme temperature applications, especially when freezing. If the electrical contacts of the system are exposed, oil with insulating properties is the ideal choice.
