The Flowmaster 250 is a portable electromagnetic flow and pressure meter manufactured by Delta Fire. It is designed for fast, accurate measurement of water flow and pressure in firefighting, hydrant testing, and water distribution systems. It connects directly to a hydrant or hose line and provides instant readings with minimal water loss during testing. It can measure flow rates up to 3000 litres per minute and pressures up to 25 bar, using electromagnetic sensing technology for high accuracy and reliability even in challenging water conditions.
The MkII is the updated version of the Flowmaster 250, featuring improved electronics, a more advanced user interface, and enhanced accuracy and usability. The MkII uses a debris resistant no moving parts electromagnetic sensor and provides a clearer display, improved data handling, and optional extended functionality such as data logging depending on configuration. In simple terms, the original Flowmaster 250 focuses on core flow and pressure measurement, while the MkII improves durability, display clarity, and operational features for more advanced field use and reporting.
The Flowmaster 250 provides real time measurement of water flow rate in litres per minute and system pressure in bar. It delivers instantaneous readings, allowing operators to assess hydrant performance, pump output, and system capacity quickly and accurately during testing or operational checks.

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
