The bay on the controller’s side accepts any of Teledyne Isco’s 700 Series Modules. The 700 Series includes:

•701 pH Parameter Module for monitoring pH and temperature.

•710 Ultrasonic Module for monitoring a flow stream’s level and flow rate with an ultrasonic level sensor.

•720 Submerged Probe Module for monitoring a flow stream’s level and flow rate with a submerged probe.

•730 Bubbler Flow Module for monitoring a flow stream’s level and flow rate with a bubbler system.

•750 Area Velocity Module for monitoring a flow stream’s level, velocity, and flow rate.

•780 4-20mA Input Module for interfacing to non-Isco devices with 4 to 20 milliampere output signals.

The modules are optional accessories, and are not required for operation. However, the modules offer a number of advantages: they are an economical way to combine flow rate or parameter monitoring with sampling, and you can program the samplers and modules as a single unit. Finally, the samplers store the readings in memory.

As an option, the sampler accepts up to 16 parameters from up to ten sensors with SDI-12 addresses from 0 - 9 (refer to SDI-12 Sonde Readings, page 1-10, for specific parameters).

The data parameters used by the sensing device (sonde) and recording device (sampler) must match. Certain vendors’ sondes have enhanced commands that facilitate “plug and play” setup. These Isco Ready sondes can tell the 6712FR what values they have, their order, and units of measure. Other sondes can be used, but require manual setup to identify proper data types for each data value reported.

The samplers contain enough memory to store five sampling pro- grams, sampling data, Isco 700 Series Module readings, and SDI-12 parameter readings. You can view the readings on your sampler’s display.

You can also retrieve the readings and reports so the information can be processed on a personal computer. Readings and reports may be collected with a computer running Teledyne Isco’s Flowlink™ software. Flowlink can download the information through a direct connection, a modem connection (when the sampler is equipped with the optional dial-out modem or con-
