The Flowmaster 250 with integrated Data Logger provides automatic recording of flow and pressure data enabling the user to collate current and historic hydrant conditions. Data is stored in a flash memory and not lost when the unit is switched off.
*Please Note
Available with any International Inlet/Outlet Adaptors


The Flowmaster 250 with Data Logger is a portable electromagnetic flow and pressure measurement device designed for hydrant testing, fire service applications, and water system analysis. It not only measures real time flow and pressure but also automatically records and stores test data for later review, reporting, and compliance purposes.
The integrated data logger allows users to capture both current and historical flow and pressure readings. This enables trend analysis, hydrant performance evaluation, and formal reporting for water network or fire system testing. The data is stored in internal flash memory so it is not lost when the unit is switched off, providing reliable long term record keeping for operational and compliance use.
Recorded data is transferred from the Flowmaster to a computer via a USB connection. Once connected, users can download logged files and use them to generate graphs, spreadsheets, and reports. The system also allows live viewing of flow and pressure data on a PC while connected, giving both real time monitoring and post event analysis capability.

Delta fire is highly recommended my me.

Fantastic equipment and customer service. Would high recommend Delta Fire to any company looking for fire service equipment. After doing a lot of market research, I found and contacted Delta Fire to get more information about their equipment. Any questions I had where answered, they helped me look at my company's needs and pick which products where best suited. Extremely helpful. To add the very long warranty and that they are UK made is what separates the from the rest. Thank you guys for all your help. 10/10
