Overview

The 515 CB01 application is a blending controller measuring the blending flow a in main and process line using frequency flow inputs.

The blending controller can operate in PRESET, ON-OFF (manual) and RELEASE mode of operation. The latest mode allows for easier tuning of the control loop.

The main and process flows are used to determine the net volume flow. The operator can view the ratio of totals as well as the ratio of flowrates.

The control of the process flow is via a digital control valve. The flowrate deadband and control responsiveness can be adjusted to reduce wear on valves.

 

Calculations

Blend Point Location.

The controller caters for blending points before and after the main flowmeter. The process flow is a ratio of the net (combined) flow (o-80% range).

Pflow
Ratio%  =  —————- × 100
                            Netflow

During the delivery the ratio setpoint is modified to cater for the flush volume:

                                                            Preset
SP ratio (mod.) = P ratio   —————-
                                                    Preset – Flush

Displayed Information

The front panel display shows the current values of the input variables and the results of the calculations. A list of the variables for this application and their type (total or rate) is shown at the end of this document.

The instrument can be supplied with a real-time clock for storage of up to 100 transactions with time and date stamps.

Communications

There are three communication ports available as follows:

  • RS-232 port (standard)
  • RS-485 port (advanced option)
  • Infra-red port (on front panel)

The ports are available for remote data reading, printouts and for initial application loading of the instrument.

Isolated Outputs

The opto-isolated outputs can retransmit any main menu variable. Totals are output as pulses and rates are output as pulses and rates are output as 4-20mA signals. Alternatively, the outputs can be configured to provide application specific digital signals like flow error, pump demand, etc.

Relay Outputs

The relay outputs 3 and 4 control the blending flow via a digital control. The relay output 2 provides a pump demand conact and relay 1 can be used as a fully programmable alarm for any rate type variable.

Software Configuration

The instrument can be further tailored to suit specific application needs including units of measurement, custom tags, second language or access levels. A distributor can configure these requirements before delivery.

Instrument parameters including units of measurement can be programmed in the field, according to the user access levels assigned to parameters by the distributor.

All set-up parameters, totals and logged data are stored in non-volatile memory with at least 30 years retention.
