Model 515 Application BF01 Dual Stage Batch/Flow Controller for Volumetric Frequency Flowmeters The 515 BF01 application is a batching flow controller for delivery of preset quantities at preset flowrates using a volumetric frequency input. Batch control can operate in preset or on-off modes, while flow control can be set to local (manual) or PI loop mode. The total and flowrate are derived from accurately measured frequency and the number of received pulses. Tailored for volumetric frequency flow input Single or Dual stage control Preset or manual On-Off modes Easy access to batch and flow rate presets No-flow, leakage and overflow error detection Remote RUN/STOP/RESET Allows for permissive with prompt Uses PI Loop Control Allows for non-linear correction Storage of 1000 transactions with time and date stamp Selection of second language and user tags Selectable protocols on serial ports including Modbus RTU and Printer output Backlit display with LCD backup This application provides the operator with clear local readout including flowrate deviation and can be controlled via communications in more automated systems. There is quick access to commonly used preset values directly from the front panel if access has been authorized. volume = pulses / k-factor volume flow = frequency / k-factor Automatic overrun compensation calculates the new valve closure point to ensure correct delivery by averaging the overrun amount from the last three complete batches. The overrun compensation value is valid for a new preset value provided the stored overrun is less than 20% of the new preset. The PI control of the process flow is via a 4-20mA proportional valve or pump controller. It has integral windup protection, a deadband, output hold and ramp time that can be programmed to reduce wear on valves and actuators and provide for bumpless operation.

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 1000 transactions with time and date stamps. 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...
