TL30 Livello Acqua CruzPro

CruzPro TL30 level indicator, for 3 water tanks, high and low level alarm, transfer pump control, Litre, Gallon or percentage reading.


Unlike the TL55, the CruzPro TL30 can monitor the level of 3 different tanks. The reading can be expressed in Litres, Gallons or in percentage. Compatible with the most common level sensors VDO, Teleflex, Mercury, GM, Stewart-Warner, Centroid, Aero-Tec and many others. It can work with American and European type sensors with resistors from 0-30, 0-70, 0-90, 10-73, 10-180, 33-240, 40-250 Ohm and vice versa. It is possible to select a high and low level alarm for each of the 3 tanks. Once activated, an 85 dB alarm will sound and the display will flash.

One of the rear panel terminals can be set as NMEA 0183 output, as external alarm output or to activate a water transfer pump within the set maximum and minimum limit.

For a better view of the display, 5 levels of backlighting can be selected. It also has a permanent memory for storing all settings, calibrations and alarm values. Even if the indicator is calibrated by the house, the user can modify these settings according to the installation needs. By pressing the front keys, you can scroll through the readings of the various tanks.
