W.E. Anderson Div., Dwyer Instruments Inc., Michigan City, IN, offers the Series MULS miniature ultrasonic level switch that measures liquid at a single point. The device uses ultrasonic wave propagation between the transducer gap to sense the presence or absence of a liquid and provides multiple output choices (SPST NO dry contact relay, NPN sinking transistor, or PNP sourcing transistor) for high/low level alarm, overflow prevention, and pump protection. Units can be mounted within 15° of horizontal with no additional calibration required. Switches have a 0.5 s time delay and <2 mm repeatability.
