Application |
| The general purpose three-wire ultrasonic transmitter provides non-contact level measurement up to 40' or 12.2 m with an internal relay that can be configured as a single-point alarm or latched on two points for automatic fill or empty control. The transmitter is ideally suited for challenging corrosive, slurry or waste liquids and is typically selected for large atmospheric bulk storage and waste sump applications. Media examples include sulfuric acid and resin.
