Many process analyzers are performing multiple jobs in individual packages

On-line water hardness measurement

Liquiline System CA80HA hardness analyzer provides precise online analysis of water hardness in drinking and process water, and helps optimize control of water softening processes, such as ion exchange or reverse osmosis; ensures quality of products influenced by water hardness; and analyzes feedwater used in boilers.

CA80HA has a colorimetric analyzer that uses the phthalein purple method, ensuring direct comparability to lab results. It measures calcium carbonate (CaCO3) over a range of 0 to 80 mg/l with accuracy of ±0.5 mg/l. The analyzer has up to two measuring channels and up to four digital inputs for optional Memosens sensors such as pH, ORP, conductivity, oxygen, chlorine, turbidity, etc.

With optional sensors, CH80HA can:

  • Measure and calculate pH from two conductivity values according to VGB Standard 405 forboiler feedwater;
  • Measure the difference between two measured values from different sources to monitor membranes;
  • Calculate differential conductivity to monitor the efficiency of ion exchangers;
  • Calculate degassed conductivity for process controls in power plants; and
  • Calculate rH from the measured values of a pH and an ORP sensor

Outputs from CA80HA can be used to directly control water processes as the process variables in a control loop; be assigned as a measured variable to a limit contactor; trigger cleaning; be sent to a control system for further analysis; and/or be displayed on the local graphic display, which has 240 x 160-pixel resolution, red display background for alarms and user-definable measuring menus.

Outputs include Profibus DP (Profile 3.02), Modbus TCP, Modbus RS485, EtherNet/IP and up to four 4-20mA current outputs that can be used in parallel.

When Memosens sensors are installed in the system, they're auto-recognized by Liquiline's electronics, making for plug-and-play operation and quick commissioning. Any changes to the electronics can be made by simply adding or subtracting I/O modules, making this plug-and-play as well. The analyzer is designed for automatic cleaning and calibration, eliminating the need for user intervention to perform these activities, reducing the overall operating cost.

CA80HA also complies with harmonized European, Canadian and U.S. standards, including CAN/CSAC22.2 No. 61010-1-12 UL Std. No. 61010-1 (3rd edition).


Hybrid laser for low-cost continuous emissions monitoring

Rosemount CT4400 continuous gas analyzer is reported to be the first purpose-built quantum cascade laser (QCL) and tunable diode laser (TDL) analyzer that measures standard components, such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), carbon dioxide (CO2) and oxygen (O2).

Optimized for cold and dry applications running at ambient pressure, CT4400 analyzer offers QCL/TDL technology, including high sensitivity, accuracy, improved stability and low-drift performance in a configuration that allows fast, easy integration into existing plant infrastructure.

Because it can hold up to four laser modules, CT4400 can measure up to seven application-specific gas components simultaneously, providing flexibility in continuous emissions monitoring systems (CEMS) applications. This simultaneous, multi-component analysis in one analyzer reduces the need for and cost of multiple analyzers.

The heart of Rosemount CT4400 is QCL technology, which detects gas molecules in the near- and mid-infrared wavelength ranges. It employs a patented laser chirp technique that enables detection of individual gas species, free from the cross-interference effects of other gas components in stream, making the measurement highly accurate and stable down to sub ppm concentrations.

Cross-pipe version of TDL

GPro 500 cross-pipe, tunable diode laser (TDL) gas analyzer solves typical TDL alignment issues by combining its laser source and receiver into one unit. A probe attached to the sensor features a corner cube at its end that redirects the laser beam back to the sensor, which means loss of alignment isn't possible. The 2D corner cube array is positioned in the pipe, opposite the analyzer head. Exact alignment isn't required because, as long as there's a straight path between the two parts, the laser will hit the array and the beam will be directed back to the photodiode in the analyzer. The probe concept is reliable in stacks with a diameter of less than one meter. For wider stacks where gas concentration isn't constant, GPro 500 has extended its family's application coverage.
