Application |
| Offered in CSA and Cenelec approved intrinsically safe or general purpose configurations, the two-wire ultrasonic transmitter provides non-contact level measurement up to 18 feet or 5.4 meters, and is ideally suited for challenging corrosive, slurry or waste liquids. The transmitter is typically selected for atmospheric bulk storage, day tank and waste sump applications located within a classified hazardous area. Media examples include diesel fuel and hydrochloric acid. See matrix to the right for more details. |
