Dry 3-1/5 in. (3.2") Water Pressure Gauge
This Dry Dial 3-1/5 (3.2") Water Pressure Gauge is designed to deliver 1% Full-Range accurate pressure ratings in a range of -30-400 PSI in wet-pipe fire sprinkler system and other water-based systems testing. This gauge has a 1/4 in. NPT connection that threads quickly testing equipment. National Institute of Standards and Tehcnology (NIST) Certificate Available.
Why Do I Need a Water Pressure Gauge?
Water pressure gauges are essential components for monitoring the water supply and ensuring that adequate pressure is maintained to effectively operate the sprinkler system.
During normal operation, the water gauge provides a visual indication of the water pressure in the system. It allows the building owners, maintenance personnel, or fire safety professionals to verify that the pressure is within the desired range for proper sprinkler system functionality. Adequate pressure ensures that water will be discharged from the sprinkler heads when activated, effectively suppressing, or controlling a fire.
Regular monitoring of the water gauge is important to identify any abnormal fluctuations or drops in pressure, which could indicate potential issues such as leaks, valve malfunctions, or water supply problems. If the water gauge shows an abnormal reading, it should be investigated and addressed promptly to maintain the reliability of the fire sprinkler system.
Why Do I Need a Gauge for Testing?
Gauges for water-based system testing in fire protection typically refer to pressure gauges used to measure and monitor water pressure during testing and commissioning of fire sprinkler systems or other water-based fire protection systems, including flow testing, hydrant flow testing, and testing using a pitot kit. These gauges are designed to withstand the pressure and provide accurate readings for testing purposes.
During water-based system testing, these gauges are connected at strategic points to measure water pressure and verify if the system is operating within the required specifications. They assist in assessing the system's performance, identifying any deficiencies or abnormalities, and making necessary adjustments to ensure the proper functioning of fire protection systems.
Which dial ranges should I choose?
The gauges in this flow test kit is available in multiple dial ranges. To prolong your gauge’s life, choose a range that places your expected pressures at the center of the dial or in the mid-range. For example, for testing outlets with 30 PSI choose a 0-60 PSI gauge range or for testing outlets with 50 PSI choose a 100 PSI gauge range.
