The Laureate™ 1/8 DIN Digital Panel Meter batch controller
is a low cost, powerful and highly accurate batching controller for repetitive fill operations. It can use the Laureate FR dual channel pulse input signal conditioner for use with turbine flow meters. Relay control can be provided by two or four 8A contact relays, or by two or four 120 mA AC/DC solid state relays. Fill operations are repeated continually with a programmable delay from 10 ms to 199.99 sec, or based on an external control input.
Three items are tracked by the batch control software. These can each be scaled to engineering units of total or flow rate and displayed by the controller's six-digit LED display: Item #1 is the current batch total, which can be set up to count up from zero to a preset limit, or down from a preset limit to zero. Item #2 can be assigned to grand total or number of batches. Item #3 is the flow rate.
Laureate Digital Panel Meters are easily programmed with Laurel’s free Instrument Setup Software, downloadable from our website and compatible with Windows PCs, requiring a data interface board for setup.
All signal conditioner board ranges are factory-calibrated, with calibration factors for each range securely stored in an onboard EEPROM. These factors can be scaled via software to accommodate external shunts, enabling field replacement of signal conditioner boards without necessitating recalibration of the associated digital panel meter. For optimal accuracy, factory recalibration is recommended annually. All Laurel Electronics instruments undergo factory calibration using the industry-leading Fluke calibrators, which are recalibrated yearly and certified traceable to national standards, ensuring the highest level of precision and reliability.
Two or four relays can be used. Relay #1 is assigned to batch total to control the filling operation. Relays #2, #3 and #4 can each be assigned by the user to Items #1, #2 or #3. For example, Relay #2 can be assigned to Item #1 (batch total) with a lower setpoint to serve as a pre-warn and slow down the fill rate near the batch setpoint, and Relay #3 can be assigned to the total number of batches to terminate the batching when a present number of bottles have been filled.
An optional serial communications board allows the batch controller to transmit Items #1, #2 and #3, as well as peak for item #3 (rate). If required, all four items can be displayed simultaneously by augmenting the batch controller with up to three Laureate remote displays. Each of these can have its own analog output and relays for alarm or control.
Batch Control with Turbine Flowmeters
The pulse-input batch controller utilizes the FR dual channel signal conditioner, which accepts pulses from turbine flow meters and most industrial transducers with a pulse output such as proximity switches with PNP or NPN output, TTL or CMOS logic, or magnetic pickup pulses down to 12 mV. The same signal is applied in parallel to the A and B input channels, which are used independently. Either channel can accept pulse rates from 0.005 Hz to 250 kHz, which exceeds the working range of turbine flow meters.
Channel A is used for totalizing. The measured total is scaled mathematically for control and display of volume in engineering units, such as liters.
Channel B is used for rate. The pulse frequency is determined by timing an integral number of periods over a specified gate time (plus 30 ms and 0-2 periods), and then taking the inverse of period. The inverse period approach allows much greater accuracy and faster update times than conventional rate meters which count signal pulses over a specified time interval. Update times can be as high as 25/sec. Rate in engineering units, such as liters per second, is obtained by multiplying the input by a scale factor.
Digital signal filtering modes can be selected to ensure stable readings in electrically noisy environments.
An unfiltered selection provides true peak and valley readings and aids in control applications.
A batch average filter selection averages each 16 conversions.
An adaptive moving average filter selection provides a choice of 8 time constants from 80 ms to 9.6 seconds. When a significant change in signal level occurs, the filter adapts by briefly switching to the shortest time to follow the change, then reverts back to its selected time constant. An Auto setting selects the time constant selection based on signal noise.
Peak and valley values are automatically captured. These may be displayed via a front panel pushbutton command or control signal at the rear connector, or be transmitted as serial data.
Two rear panel control Inputs (CMOS/TTL levels, logic 0 = tied to digital ground, logic 1 = open) or dry contacts that can be set to control / activate 14 meter commands.
An (isolated) 5, 10, 12, or 24 Vdc excitation output is standard to power transducers or two-wire transmitters. Ratiometric operation, which automatically compensates for changes in the applied excitation, is jumper selectable for applications, such as bridges, where the signal to be measured is proportional to the excitation level.
Modular Design for Maximum Flexibility at Minimum Cost
All boards are isolated from meter and power grounds. Optional Plug-in-Play boards for communications and control include Ethernet, WiFi, serial communication boards, dual or quad relay boards, and an analog output board. Laureates may be powered from 85-264 Vac or optionally from 12-32 Vac or 10-48 Vdc. The display is available with bright red or green 0.56" (14.2mm) high LED digits. The 1/8 DIN case meets NEMA 4X (IP65) specifications from the front when panel mounted. Any setup functions and front panel keys can be locked out for simplified usage and security. A built-in 5, 10, 12, or 24 Vdc excitation supply can power transducers, eliminating the need for an external power supply. All power and signal connections are via UL / VDE / CSA rated screw clamp plugs.
The Laureate™ Series features modular design with up to 7 isolated plug-in boards, applicable to all Laureate 1/8 DIN Digital Panel Meters.
Modular Hardware
The design of the Laureate™ Series is modular for maximum flexibility at minimum cost. All boards are isolated from meter and power grounds. The base configuration for a panel meter or counter consists of a main module (with computer and plug-in display boards), a power supply board, and a signal conditioner board. Optional plug-in-play boards include an isolated setpoint controller board, an isolated analog output board, and an isolated digital interface board. Modular design and a choice of plug-in options allow the Laureate to be customized for a broad range of applications from simple monitoring to control and computer interface. There can be up to five plug-in boards in a 1/8 DIN Laureate.
Connecting Laureate Digital Panel Meters to a Local Area Network (LAN)
Up to 30 Laureate Digital Panel Meters and/or LT Transmitters can be configured for RS485 and daisy-chained to an LT Transmitter using Laurel’s High Speed Ethernet-to-RS485 converter board for seamless LAN integration. Alternatively, Laurel LTE series Ethernet transmitters can connect directly to a LAN via an Ethernet cable. Setup for both configurations is streamlined using Laurel’s free Instrument Setup Software, which simplifies node discovery and transmitter configuration.
Flexible Communication Options for Digital Panel Meters
Laureate Digital Panel Meters can be equipped with Laurel communication boards to support various interfaces and protocols. These include serial interfaces with ASCII or Modbus RTU protocols, and Ethernet interfaces with web access, ASCII, or Modbus TCP/IP protocols, ensuring versatile connectivity for your commercial applications.
