Flow Meter

Flow Meter for Fire Water System Measurement

A flow meter measures water moving through compatible pipework and provides an indication or output according to the selected instrument design. Installed in the intended flow path, it can support observation, commissioning, testing and maintenance activities within a properly engineered fire water system. The instrument reports flow-related information; it does not establish system capacity or confirm compliance on its own.

Coordinate the measuring point with AJ Safety Solutions, review the related gauges and instruments, and plan access using the available testing and maintenance information.

Inline Water Measurement

The meter body is installed so water passes through its measurement section in the correct direction. Depending on the model, the sensing principle and display may be mechanical, electronic or a combination of both. Straight-pipe requirements, orientation, upstream disturbance, water quality and accessibility can influence installation and usable readings.

Functional Features

• Measures water flow at a defined pipework location.
• Provides a local display or project-specific output interface.
• Directional marking assists correct installation in the flow path.
• Supports planned testing and comparison with approved system information.

Typical Applications

Flow meters may be coordinated with fire pump test arrangements, hydrant pipework, hose reel systems, water supply lines and other approved fire protection installations. The selected instrument must suit the intended measurement task, pipe arrangement and environmental conditions documented for the project.

Specification and Installation Notes

Measurement range, pipe size, connection type, pressure class, accuracy, turndown, display format, output signal, power requirement, body material, installation length, environmental rating, certification and approvals vary by model. No numerical performance or universal compatibility is asserted here. Confirm the complete data sheet before ordering, installation or publication.

Inspection and Standards Context

Keep the display visible, confirm flow-direction marking, inspect joints for leakage and maintain access for verification. Consult NFPA 14 for relevant standpipe and hose system requirements and NFPA 25 for inspection, testing and maintenance guidance. Approved designs, adopted codes, manufacturer instructions and the authority having jurisdiction determine the final arrangement.
