Benefits and key reasons to choose this level gauge Prevents overflow and dry run: builtin , low and emptytank alarms notify you before problems occur, protecting pumps and stored water. Quick, ataglance readings: a digital bar graph shows water depth from 0 to 4.75 meters in 10% increments so you can assess tank status instantly. Flexible installation and reliable monitoring: a wireless transmitter/receiver link up to 100 meters in open areas removes the need for long cables and simplifies placement. What it does (functions and performance) Measures water depth from 0 to 4.75 meters and displays the level as a digital bar graph that updates in 10% increments for clear visual feedback. Issues audible/visual alarms for level, low level and empty tank conditions to prevent overflow or dry operation. Transmits data wirelessly between transmitter and receiver over a 433 MHz link, supporting reliable communication up to 100 meters in open areas. Receiver includes a backlit LCD for easy daytime and nighttime reading, and can be mounted on a wall or used on a tabletop. Durability, installation and compatibility Transmitter housing is IP65 rated for weather resistance, suitable for outdoor installation. For performance place the transmitter centered horizontally above the tank as recommended. Works with the included matched transmitter and receiver using the 433 MHz protocol; ideal for standard gravity or storage water tanks where remote level monitoring is needed. Practical applications Home water storage: monitor rooftop or basement tanks to avoid pump damage and ensure consistent household water supply. Agriculture and irrigation: keep track of field or silo water levels to schedule refills and protect irrigation pumps from running dry. Rainwater harvesting and remote sites: use on tanks at remote properties, cabins or construction sites where wired monitoring is impractical.
