Stalgast Water Flow Meter 823850 for Filter Monitoring

A water flow meter measures the rate at which water passes through a pipe and accumulates the total volume used. It mounts inline on the supply line, where a turbine or paddle wheel turns with the flow. Each rotation corresponds to a fixed volume, so the meter counts rotations to calculate both instantaneous flow and cumulative usage. This method gives consistent readings regardless of pressure fluctuations, making it suitable for monitoring filter performance in professional kitchens.

The operator connects the meter to the water line with a 3/8 fitting, then powers it on with the included AAA batteries. The display shows the current flow rate in litres per minute and the total volume that has passed through. When the programmed volume limit is reached—up to 99.500 litres—the meter sounds an audible alert, signalling that the filter element needs replacing. The unit continues to measure flow and volume until the batteries are depleted or the limit is reset.

The body is constructed for inline installation on water lines. It accepts a 3/8 connection and handles flows between 1.5 and 14 litres per minute. Controls consist of a display and buttons for setting the maximum volume threshold. The maximum programmable volume of 99.500 litres allows long intervals between filter changes, while the 1.5–14 L/min flow range covers typical tap and appliance demands in catering settings.

Cleaning involves removing the meter from the line and wiping the exterior with a damp cloth. The internal mechanism requires no maintenance beyond battery replacement. The meter is compatible with Stalgast filter models 822060, 822080 and 822850, where it replaces manual tracking of filter life.
