Kobold KAL Thermal Flow Switch

	Three units are available. Each is compatible with the full series of sensors. Electronic circuitry is located in a standard DIN housing (NEMA 1) for quick installation on terminal rails.
KAL-E100 Series	The KAL-E100 is equipped with a flow rate sensitive, isolated SPDT relay. The relay status is indicated by means of a green LED.
KAL-E200 Series	Same as the KAL-E100, but with a trend indicator for flow rate and switch point.
KAL-E300 Series	Same as KAL-E200 but with a temperature switch. In addition to monitoring the flow, this model can be used to monitor the temperature. The specified alarm temperature can be from 0–176 °F. SPDT relays are activated if the flow drops below the specified flow velocity, or if the temperature drops below the specified temperature.
