The MF5700 features cost effective ultra-low power operating on 4 AA batteries. The portable design has excellent exchangeable mechanical adaptors, easy data accessible and user programmable capabilities. The internal data storage can also help for many industrial on-site applications. The meters can be customized for various general purpose flow applications. LCD output is included along with an optional RS485 output.
Equipped with a manual flow needle valve, high precision adjustment of the flow rate. Recommendation: Needle valves precisely regulate flow after pressure stabilization.
