Site Assessment

Reservoir, Pond and Weir Flow Sites

• Is there a reference water level measurement

• Will the wildeye location experience flooding? If so, do not use vented sensor

Sensor Interface Connections

Connection Types & Physical Output Port

The Level TROLL may be connected to a controller or logger for
communication via:

• Analog (4-20 mA)

• SDI-12

• RS485 Modbus

• RS232 Modbus (with a customer-supplied converter)

RuggedCable® stripped & tinned cables have a “female” Twist-Lock
connector on one end to mate with the Level TROLL body. The uphole
end terminates in bare wires for connection to a PLC or data logger.
Also available in a shorter length ending in a “male” Twist-Lock connector
to mate with RuggedCable systems.=

Electrical Connections

When using SDI12 - make sure the 2 MODBUS wires are connected to ground!!

Otherwise, a stray signal on the modbus interface will shutdownt the SDI12 comms, and activate the MODBUS comms

4-20mA Interface (2-wire)

Interface Details

• 4-20mA - Stabilization Time: 250ms
