Darley Hydrant Testing Piezometer with Dry Pressure Gauge

The Darley Hydrant Testing Piezometer is a brass piezometer assembly used to take flowing pressure readings during fire pump and hydrant testing. It measures velocity pressure to determine how much water can be delivered from outlets up to 8 inches in diameter, supporting accurate evaluation of firefighting water supply performance.

Features

• Construction: All brass tube design for durability during testing operations
• Valve: Integrated bleeder valve for controlled pressure release

Performance Features

• Measurement: Captures velocity pressure for accurate water flow calculation
• Capacity: Suitable for outlets up to 8 inches in diameter

Standards and Compliance:

• Compliance: Made to Underwriters Laboratories specifications

How Is It Used

This piezometer is used during pump and hydrant testing to measure flowing pressure rather than static pressure. By capturing velocity pressure, it supports accurate calculation of water flow and overall firefighting water delivery capability.

Intended For

Used in flow testing operations to evaluate the firefighting efficiency and water delivery performance of fire pumps and hydrant systems.

Maintenance Information

The brass construction and dry gauge are designed for durability during testing operations. Proper handling during use and storage helps maintain gauge accuracy and overall performance.

Storage Information

This product should be stored in a dry, protected environment when not in use to help preserve gauge accuracy and component condition.
