Description

A sounding transmitter is located on top of the tank or silo to be measured. A plummet (float or weight) is lowered until it touches the process material and is then retracted. The distance traveled is computed and transmitted as a signal representing level or volume. The signal may be remotely displayed and can be direct reading in engineering units. All calibration, configuration, and test data reside in the memory of the sounding transmitter. The remoted operate/display device is inherently very simple and easy to setup and program. Each sounding unit(s) may be operated by multiple remoted devices in separate locations. The operating device may be a PLC, Model 825, host computer, or a combination of these.
