Overview
Hedland H625-028 is a reliable, mechanical flowmeter designed for real-time flow monitoring in liquid systems. The Hedland EZ-View flow meter is a direct-reading, variable area flow meter that provides instantaneous flow rate measurement without the use of electronics. Made from high-impact thermoplastics, the Hedland® EZ-View® flow meter contains a minimum number of moving parts, offering a reliable and trouble-free flow rate indicator. This unit is sized for the 4.0–28 GPM range and features a 3/4″ NPT male thread connection.
Key Features
- No Electronics Required: Direct-reading mechanical operation provides flow visibility without power, wiring, or signal conditioning.
- Thermoplastic Body: Constructed with a high-impact polysulfone plastic body allows visual inspection of fluid condition, useful for preventive maintenance and system diagnostics.
- Flexible Installation: Can be installed in any position or orientation and does not require special piping or flow straighteners during implementation.
- Wide Application Range: Available in brass, stainless steel and PVC, with NPT and BSP ports, allows the meter to be installed in a wide variety of applications, including oil and water processes.
- Minimal Maintenance: Simple internal design reduces wear and service needs.

Typical Applications
The H625-028 is commonly used in cooling loops, circulation systems, and process fluid monitoring where reliable mechanical flow indication is required. It suits water cooling circuits, HVAC systems, industrial wash-down equipment, and any application requiring non-electronic flow verification. The thermoplastic body and NPT thread make it adaptable to both permanent and portable flow measurement setups.
