The D-Series Flow Monitor
The Fletta Flow Monitors' function is based on the proven and dependable differential pressure principle. This is perhaps the oldest and most widely used principle for flow metering, mainly because of it's simplicity and its relatively low cost.
The Eletta D-series Flow Monitor is used to control flow of liquids and gases in pipes from 15 mm to 500 mm. With two relay contacts, independently adjustable within the ordered flow range, you can protect expensive equipment in various piping systems. The switching point is highly repeatable, within <2%. The D-series has the long-standing proven mechanical function with outstanding reliability. The exceptionally sturdy and robust design makes it extremely well suited for difficult environments.
The D-series comes in two measuring ratios which means that the D2 has a mesuring span of 1:2 and the D5 has a span of 1:5. The 1:2 measuring D2 also has a Low Pressure variant called D2-LP, which can measure flow at line pressure as low as 100 mbar, as it creates a rather low DP of just 50 mbar at max flow. This is useful for measuring gravitational flows from overhead tanks and Air Blowers kind of low pressure applications. The highest flow measuring range for D2-LP is typically half of the standard D2. Like all Eletta Flow Monitors the D-series can monitor both liquids and gases.
