Industrial 100A 100-2-R Water Flow Meter 1 Inch NPT

The Carlon 100A 100-2-R Electric Contacting Water Flow Meter is a 1" NPT inline displacement meter with a dry-contact reed switch output, designed to connect to low-power controls without external power for the sensor. It counts water flow in units of 100 gallons per contact (100 GPC), making it well-suited for dosing, batching, or usage monitoring in industrial or residential water applications. The reed switch is normally open and rated for up to 24 V and 100 mA, enabling straightforward interface to batch controllers and data-logging equipment. Constructed for cold-water service with corrosion-resistant materials, the unit fits standard 1" piping and integrates with Carlon batch-control workflows where an electric-contacting meter is used to generate pulse signals for totalization and control.
