IQ SensorNet Family

On-line Monitors







The IQ SensorNet system from WTW represents a major landmark in the development of water quality monitoring and control systems.


Its modular nature combined with the "intelligent", self recognition digital sensors gives YOU ultimate flexibility to specify any combination of parameters and meter functions that suit your application.

Up to 20 sensors measuring any combination of 16 parameters can be monitored, logged and transmitted from a single meter that can display data from up to 8 sensors simultaneously. A removable screen allows local calibrations at any measuring point with instant connection to the system network. A wide range of power and communication options are available. Adding a measuring point couldn’t be simpler – simply cut the cable linking the network and add a new measuring point for any parameter. The system instantly recognises the sensor data and the new sensor is instantly part of the network. – It’s really that simple.

IQ SensorNet has three levels of meter /controller : 182, 184 XT and 2020.

DIQ/S 182 allows up to 2 sensors to be connected and monitored. It has both relay contacts and 0 – 20 or 4 – 20 mA outputs. Communication options include Bluetooth radio, and RS485. Power supply can be 110 – 240 V AC or 24 V AC or DC

MIQ/S 184 XT allows up to 12 sensors to be connected and monitored. It has an internal logger allowing stored data to be displayed to reveal trends in sample characteristics. You can choose modules to add a huge range of functionality including logged data transmission, air cleaning valve control, analogue outputs and relay controls.

MIQ/T2020 allows up to 20 sensors to be connected. In addition to the features of the 184 XT it has a mobile display that can be disconnected and reconnected at any point in the system network to allow local calibration and a modem-capable RS 232 interface.
