The Kobold SM series is a variable area device that can be ordered as a flow switch, flow meter, or combined switch and meter. The flow switch is mounted externally in a protective housing, and is actuated by magnet in the float. This same magnet can also be used to couple to an external flow indicator, allowing a visual reading of the instantaneous flow rate. The meter can be configured with either or both of these features to fit a wide variety of applications.

Kobold SM series flow meters and switches benefit from all the advantages inherent in using an all metal construction (high pressure, shock resistance). They are designed to handle flow rates higher than their stated maximum flow range without damage. At excessive flow rates the device will, however, induce a larger pressure drop. Accuracy is ±4% of full scale for both liquids and gases. Maximum pressure depends on construction: brass 3600 PSIG, stainless steel 5000 PSIG, and models with PP floats 230 PSIG. Maximum temperature is 240°F.
