Watchlog Wireless Turbine Flow Meters

Turbine flow meters fitted with Watchlog Wireless transmitters send measuring data to the BSx series signal receiving base stations.  2x AA batteries give up to 2 years of battery life. Adjust scanning and data transmission speeds via Watchlog Wireless software.

This range of flowmeters is used for liquids such as water, light oils, solvents and low viscosity chemicals.

You can use them for batching, flow rate monitoring, controlling, blending and filling. The flowmeter is highly accurate and often used for testing the performance of pumps, engines, valves and other flowmeters.
