Flowmaster 250 MK2 Data Logger is a high-accuracy portable flow and pressure test instrument with integrated data logging. Designed for hydrant testing, flushing, and minimum night flow measurement, it delivers flow rates up to 3000 LPM and pressures up to 25 bar with no moving parts. Rugged, lightweight, and easy to use on site.
The Flowmaster 250DL MK2 is a professional-grade portable flow and pressure test instrument designed for accurate, reliable field testing across a wide range of water network and fire hydrant applications. It delivers precise measurements of flow rates from 30 to 3000 litres per minute and pressures up to 25 bar, making it ideal for hydrant testing, water main flushing, trunk main conditioning, and minimum night flow analysis.
Built with an advanced electromagnetic sensor that contains no moving parts, the Flowmaster 250DL MK2 provides consistent, debris-resistant readings that are not affected by water quality or particulates. With a flowrate accuracy of up to 98% and pressure accuracy within ±1% of range, it delivers high-performance data you can trust for compliance and reporting.
This unit features a fully integrated data logger, allowing users to store and transfer flow and pressure results easily via USB. The clear, backlit 320 x 240 graphic colour display presents all measurement data in one place, simplifying on-site use. Its intuitive controls and compact form factor ensure ease of operation, while its robust aluminium housing offers long-lasting durability in harsh environments.
Powered by a rechargeable lithium-ion battery with up to 10 hours of operation, the Flowmaster 250DL MK2 is a truly portable solution for field engineers and utility professionals. A battery monitor provides a clear indication of remaining runtime, and an optional external battery pack can extend usage further. The instrument is supplied with 2.5” BS Instantaneous male/female connections, with a wide range of optional adaptors available to suit different regional standards.
From hydrant testing to flow verification and network analysis, the Flowmaster 250DL MK2 delivers dependable performance, data accuracy, and field-ready versatility in a single, compact unit.
