The L Series of AQUAMETA water tank level transmitters and receivers extend the current communications range of our AQUAMETA  products to 10Km. With the impending release of our new R153 repeater station, this range can be further extended by using one or more repeaters.

The L series transmitters come in 3 variations:

• LT153 Long Range transmitter. This unit will act as a relay station to any number of T434R of T434B tank units located within a 300m radius from it. Water level data received from these Tank Units will be retransmitted using the long range radio telemetry link. The LT153 will typically be used where there is more than one tank at the remote location. The LT153 is also ideal to use where the tank is located at a inconvenient location necessitating the need to have the antenna some distance away.
   

• T153B tank unit. This tank unit is equipped with its own long range radio transmitter and is used where only level information needs to be transmitted.
   

• T153R tank unit. This unit is equipped with its own long range transmitter and is used where level data as well as start and stop control signals to local, or remote pumps, or valves are required.

The L Series transmitters require 12V DC to operate.

The LR153 is the long range receiver. The LR153 can accept telemetry data from any number of the L series transmitters. The LR153 will retransmit the level data using our short range wireless link to any of our level display units such as the R1, R5 or R1SP. The benefit of using a short range wireless link to relay the data signal is that there is no requirement to wire long lengths of coax cable from the antenna to the receiver, since the design enables the receiver to be located close to the antenna.

Using the LR153 in conjunction with the R1SP allows for providing start and stop control signal to a pump or valve at a remote location.
