The Eletta V-series Flow Monitor is used to control flow of liquids and gases in pipes from 15mm to 500mm. Through the adjustable SPDT micro switch it is possible to set one low or high flow alarm to protect expensive equipment in various piping systems. The switching point is highly repeatable, within < 2%.
The Flow Monitor is insensitive to surrounding magnetic fields and it combines the long-standing proven mechanical function with outstanding reliability. Together with an exceptionally sturdy and robust design, this makes it extremely well suited for difficult environments.
The V-series comes in two measuring ratios designated V1 and V15, which means that the V1 has a flow measuring span of 1:2 and the V15 has a span of 1:5. Like all Eletta Flow Monitors the V-series can monitor both liquids and gases.
