1.0 RANGE OF USE
The TDR-1000 level gauging system is a 2 wire transmitter, designed to measure the distance, level and
volume of liquids, slurries, solids and particulate materials. It can be operated on storage and process
tanks.
2.0 Description
The measuring system consists of the sensor and the signal converter. The compact signal converter
contains the TDR measuring circuit and the entire signal processing system, including the provision of a
standardized output signal (4 - 20 mA or digital interface).
3.0 Measured variable (distance, level, volume)
The primary measured variable is the distance between the tank mounting flange and a reflecting surface
(surface of the product measured). The output represents the difference between the primary measured
variable and the length of the sensor.
3.1 Measuring range (to 78 ft)
The measuring range will depend on the sensor length, the reflection properties of the tanks contents, the
installation position, and the presence of any interfering reflection
4.0 Mounting, please refer to the following guidelines:
ENSURE THE SENSOR LENGTH DOES NOT
EXCEED THE INTERNAL DEPTH OF THE SILO,
TANK OR VESSEL.
