- 1. TI199C/07/EN/13.11 71130252 Technical Information Liquisys M COM223/253 Dissolved Oxygen Measurement Transmitter for oxygen sensors Application The modular design of the transmitter allows easy adaption to a variety of customer requirements. Starting with the basic version for "measurement and alarm generation", the transmitter can be equipped with additional software and hardware modules for special applications. These modules can also be retrofitted as required. Areas of Application • Sewage treatment plants • Wastewater treatment • Water treatment • Drinking water • Surface water: rivers, lakes, sea • Fish farming • Boiler feed water (trace measurement) Your benefits • Field or panel-mounted housing • Universal application • For analogue and digital sensors • Simple handling – Logically arranged menu structure – Simple single-point calibration in air, air-saturated water or in the medium is possible • Safe operation – Excellent interference immunity – Direct access for manual contact control – User-defined alarm configuration The basic unit can be extended with: • 2 or 4 additional contacts for use as: – Limit contacts (also for temperature) – P(ID) controller – Timer for simple rinse processes – Complete cleaning with Chemoclean • Plus package: – User-defined current output characteristics – Automatic cleaning trigger on alarm or limit violation – Process monitoring – Sensor live check • HART or PROFIBUS-PA/-DP • 2nd current output for temperature, main measured value or actuating variable • Current input for flow rate monitoring with controller shut off or for feedforward control
- 2. Liquisys M COM2x3 2 Endress+Hauser Function and system design Features of the basic version Measurement of oxygen content and of partial oxygen pressure The oxygen content is displayed in mg/l or in %SAT, the partial oxygen pressure is displayed in hPa. This is selected via the menu. The temperature is displayed at the same time or, if desired, not shown at all. Calibration The amperometric sensors are zero-current-free and only require a single-point calibration. This takes place in air, air-saturated water or by reference calibration in the medium. The optical sensor will be calibrated before shipment. If necessary it can be calibrated in air and for zero point. Configuration Different alarms are required depending on application and operator. Therefore the transmitter permits independent configuration of the alarm contact and error current for each individual error. Unnecessary or undesirable alarms can be suppressed in this manner. Up to four contacts can be used as limit contacts (also for temperature), to implement a P(ID) controller or for cleaning functions. Direct manual operation of the contacts (bypassing the menu) provides quick access to limit, control or cleaning contacts, permitting speedy correction of deviations. The serial numbers of the instrument and modules and the order code can be called up on the display. Additional functions of version WX/WS/DS Automatic pressure compensation Oxygen concentration is not only dependent on altitude but also on weather conditions (pressure). Automatic pressure compensation takes these fluctuations into account. Additional functions of the Plus package Current output configuration In order to output wide measuring ranges while still achieving a high resolution in specific ranges, the current output can be configured as required via a table. This permits bilinear or quasi-logarithmic curves, etc. Process Check System (PCS) It comprises two independent safety functions: • Errors in applications without control are detected by monitoring the limit beween plausible and implausible measured values, i.e. the alarm theshold. • Errors in applications with control are detected by the controller monitor which monitors freely adjustable, maximum permissible time intervals and reference value overshoot or undershoot. Live check, sensor activity monitoring The live check issues an alarm when the sensor signal does not change over a defined period of time. This may be caused by blocking, passivation, separation from the process, etc. Second current output The second current output can be configured for temperature, main measured value (oxygen content, partial oxygen pressure) or actuating variable. Current input The current input of the transmitter allows two different applications: controller shut-down in case of lower flow rate violation or total failure in the main flow as well as feedforward control. Both functions are also combinable.
