Newberry Clock Gauge with High-Level Alarm (SKU: CG918-0400)

Description

This clock gauge displays the liquid level of product stored in an above-ground storage tank up to 12 feet high, with an audible alarm that activates at a user-specified level. Like the standard clock gauge it reads out on a clock-style dial - hour hand feet, minute hand inches - accurate to one eighth of an inch and readable from 30 feet, installing through a single 2 inch tank top opening with a 360 degree rotating face. A stainless steel float and cable drive the hands; an internal switch trips at the operator-set alarm point and signals an intrinsically safe alarm box that produces the audible warning. The alarm point is set in the field, commonly at 95 percent full so the driver knows when to stop filling. Newberry supplies these as Morrison Bros. FIG 918---0400 clock gauges with a drop tube float.
