Alarm Module

Where a flowmeter is required to be installed and provide a set of relay contacts when an alarm point (critical rate of flow) has been attained whether this be a rising or falling flow.

Flow Switch

This simple wall, or in some cases, flowmeter mounted instrument gives an adjustable set point with a single pole, voltage free relay output. There are two hysterisis levels to prevent relay flutter at the selected set frequency input. The standard converter has an input frequency range of 0 to 1 KHz. The status LED’s on the circuit board indicates when the relay has operated and power / inputs are present. The enclosure in a high impact polycarbonate that seals the unit to IP65 (NEMA 4X). Access to the terminals is normally via a pair of glands on the bottom of the enclosure.
