Dry vs liquid filled pressure gauge:
Pressure gauges are essential instruments used to measure the pressure of liquids and gases in industrial systems. Two commonly used types are dry pressure gauges and liquid-filled pressure gauges.
Both generally use a Bourdon tube mechanism to convert process pressure into mechanical movement of a pointer. The main difference is that a dry gauge contains air inside its case, while a liquid-filled gauge contains a damping liquid, typically glycerin or silicone oil, to reduce pointer fluctuations caused by vibration and pressure pulsation.

Fire Alarm Device Installation Heights: Safety Starts with Correct Installation!
In fire and life safety systems, correct installation is just as important as selecting the right equipment. Proper mounting heights and positioning help ensure that fire alarm devices are accessible, visible, and effective during an emergency.
Key Points to Remember:
Manual call points / pull stations - install at the code-specified accessible height.
Wall-mounted notification appliances - follow applicable mounting-height requirements.
Smoke detectors - install according to the approved design, NFPA 72, and manufacturer instructions.
