PROAM - Chloride Monitor

Description

The ProAm Chloride Monitor is a simple, compact on-line analyser designed for continuous measurement. Other parameters include Ammonia and Nitrate. The instrument comprises a wall-mount analyser section with an integral sample pump; a controlling processor interfaced by a membrane keyboard and back lit LCD. Internal valving, controls the distribution of fluids during analysis and the automatic calibration / wash routines. Electrical connections for power supply and signals are externally made from a separate IP65 enclosure.

  Low cost, single stream analyser with automatic calibration/clean routines

PRINCIPLE OF OPERATION

The ProAm analyser uses an ion selective (ISE) Chloride electrode. Sample is delivered through large diameter tubing to a glass vessel containing the electrode. The sample is also temperature regulated and sparged with air to create a flow past the sensor. The integral peristaltic sample pump can deliver sample directly from source or from a fast sample loop. A series of pinch valves are configured to control the passage of sample, calibration and cleaning fluids without introducing points of blockage thus improving reliability. Loss of sample or calibration fluid is detected by an inline sensor. For process and waste water applications, membrane filtration may be integrated to remove particulate and biology from the sample to improve measurement performance.

CONTROL AND MONITORING OPTIONS

Various options are available offering different levels of automation and communication. As standard, the instrument is supplied with an analogue output with its range determined by the selected calibration values. Four change-over contact relays (volt-free) are also available; two may be configured as limit alarms and two may be programmed to indicate various fault conditions. Alternatively, data may be transmitted to telemetry using Profibus or Modbus (other protocols are available on request). The instrument may be configured for continuous or intermittent analysis and controlled remotely using the BUS system.
