Description

The RediLevel™ 2100 DLS measures and reports fluid levels and temperatures in a variety of tanks and

vessels. The sensor has a thin-profile, sturdy design to fit into tanks with two-inch ports. It is a digital

sensor as it reports the information in a serial bit stream. The sensor uses a float(s) embedded with

magnets to sense the top fluid level(s). A sensor may have one or two floats. A two-float sensor can

measure multiple fluids in a tank. There is a temperature sensor mounted inside the tube fourteen inches

from the bottom. When the sensor is polled for data, a series of microprocessors read and determine the

position of the float(s) along the sensor tube. The main microprocessor then calculates the level and

temperature and returns the data in a serial stream.

Communications

The serial communication protocol is RS485 2-wire or 4-wire, field selectable via jumpers on the fuse

board. The baud rate is set to 9600, N, 8, 1. In 4-wire mode, one pair of wires is used strictly for

transmitting and another pair is for receiving. For 2-wire mode, only one pair of wires is needed for both

transmit and receive. Two wires are needed for the power supply, therefore 4-wire communications

require a 3-pair cable while 2-wire communications require a 2-pair cable.

Wiring Connections

The sensor requires a power supply of 5.6 to 13 volts DC. To connect the sensor communication lines to

the telemetry equipment, connect the sensor data receive to the RTU data transmit and the sensor data

transmit to the RTU data receive. The voltage supply can be connected to a switched output so power is

applied only during sensor polling.

Installation

To install the sensor, follow the simple steps below while referring to the assembly diagram in Figure 2 at

the end of this manual:

Install the sensor-grip and a reducer for the tank port size that is to be used. Slide

this assembly onto the bottom of the tube

Install the float stop at the bottom of the sensor tube.

Carefully insert the bottom end of the sensor into the tank port and lower the sensor

slowly into the tank. Be careful with the float so it does not hang up on the port

edge.

CAUTION:

DO NOT drop the sensor into the tank. The sensor contains glass switches and a

sharp impact will break them, making the sensor inoperable.

With the sensor resting on the tank bottom, slide the reducer/sensor-mount

assembly down to the tank port and tighten it onto the port. Tighten the sensor

mount tight enough so the sensor cannot rotate by hand.

Unscrew the round side cover from the sensor top housing and feed the signal cable

through the cord grip on the side of the sensor top. Unplug the gray, 6-position

connector from the internal fuse board.

Make sure power is off before proceeding.
