• Description : As for leakage, a Glycerine-filled manometer always has this risk, but the risk is very low.

Overview

• 　　If your application has a very low temperature of 0 degrees or below, you can use silica gel or a mixture of glycerin and distilled water instead of pure glycerin. Both fluids can reduce the temperature to -40 degrees Fahrenheit.

  　　As for leakage, a Glycerine-filled manometer always has this risk, but the risk is very low. The possibility of leakage depends on the quality and application of the meter you are using. If you are primarily concerned about leakage, to reduce the risk, use the crimping baffle type instead of bayonet because the crimping baffle permanently holds the gasket in place and is unlikely to loosen in the field or due to human error. Similarly, due to improvements in manufacturing technology and standards, the risk of leakage is now very low. Our Glycerine-filled manometers all follow the ASME B40.1 standard to help ensure that the meters we provide meet the highest quality standards.

  　　Last but not least, let's talk about the accumulation of pressure. Pressure may be generated inside the pressure gauge, which is natural for a pressure gauge filled with liquid. An increase in pressure (usually very small) can sometimes cause the pointer to deviate from zero and/or cause inaccurate meter readings + or – 2-4%. To relieve pressure, gently lift the filling plug to hiccup the pressure gauge. When you are done, you will see the pointer move back to zero.
