Description
The APG Kari is a cable-suspended float level switch that holds up to four switch points in a single polypropylene float, so one float can replace up to four separate float switches. Twenty-five configurations cover high and low alarms, fill and empty pump control, duplex control and isolated alarms, and several models have built-in hysteresis that runs a pump directly through its starter without a separate controller.
Contacts are rated 250 V AC/DC, the float is sealed to IP67 / NEMA 6 for liquids up to 54 °C (80 °C option), and the switching differential is set by the position of the cable weight.
Argonmark Ltd supplies APG instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
