The Laureate 1/8 DIN Digital Panel Meter for dual-channel up or down totalizer
is a Standard operating mode of the Laureate counter with the FR dual-channel signal conditioner board that can display frequencies from 0.005 Hz to 1 MHz. Each channel (A or B) may be independently set up and scaled to count up from zero (or other value) to a preset limit, or to count down from a preset value to zero (or other limit). Countdown operation is set up by entering a negative scale factor.The six-digit counter display is capable of displaying any value from -999,999 to 999,999 with a programmable decimal point. Scaling allows direct readout in engineering units, such as gallons or cubic feet based on counts from a turbine flowmeter, or the count of cans based on the count of six-packs. The displayed channel (A or B) is selected via a front panel pushbutton. The totals are stored in non-volatile memory so as to be retained in the absence of power.
The minimum recommended complementary option for the Laureate totalizer is the dual setpoint controller output board, which is available with either 8A relays or AC/DC solid state relays.
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.
An Optional Extended DPM Provides Capabilities Beyond Those of the Standard Counter:
- Rate and total simultaneously. Channel A can display total while Channel B displays rate. The selection of A or B for display is via a front panel pushbutton. This mode is ideal for flow applications.
- Up/down counting. Channel A can serve as an up/down counter, where the count direction is dynamically changed by applying a signal to Channel B. For instance, Channel A can count and scale pulses from a turbine flow meter, while Channel B inputs the direction of flow. This allows total volume to be tracked in case of reversible flow.
- Totalizing with external inhibit. Totalizing by Channel A can be temporarily inhibited by applying a signal to Channel B. For instance, 60 Hz AC pulses can be counted by Channel A and be scaled to display elapsed hours. A signal can be applied to Channel B to start or stop pulse counting when a process is in operation.
- Custom curve linearization. Exceptionally accurate custom curve linearization is achievable, for example to linearize the low end of turbine flow meters. For setup, up to 180 data points can be input into a spreadsheet or text file by the user. The computer then calculates spline fit segments, which are downloaded into the meter via RS232. The linearized rate can then be totalized by the Extended counter.
- Arithmetic functions. The Extended counter makes arithmetic functions available, namely A+B, A-B, AxB, A/B and A/B-1. These solve many applications. For instance, A+B allows two input flows to be summed for total volume, while A-B allows outflow to be subtracted from inflow for net volume. A/B allows the mixing of ingredients in a specified ratio. By monitoring and alarming the A/B volume ratio, ingredient B can be added to A until the proper ratio is achieved.
The FR dual-channel signal conditioner accepts inputs from proximity switches with a PNP or NPN output, TTL or CMOS logic, magnetic pickups, contact closures, low-level outputs from turbine flow meters down to 12 mV, and high-level AC line inputs up to 250 Vac. Jumper selections provide optimum operation for different sensor types and noise conditions. A built-in (isolated) 5, 10, 12, or 24 Vdc excitation supply can power proximity switches and other sensors, and eliminate the need for an external power supply.
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.

Panel Mounting
Slide the meter into a 45 x 92 mm 1/8 DIN panel cutout. Ensure that the provided gasket is in place between the front of the panel and the back of the meter bezel.
The meter is secured by two pawls, each held by a screw, as illustrated. Turning each screw counterclockwise extends the pawl outward from the case and behind the panel. Turning each screw clockwise further tightens it against the panel to secure the meter.
Turning each screw counterclockwise loosens the pawl and retracts it into its well. This position allows installed meter to be removed from their panel, or new meters to be installed in a panel. Do not remove the screws from their pawls. Doing so would cause the screw and pawl to fall off and likely get lost. Do not overtighten so as not to damage the plastic parts.
| Up/Down Totalizing | |
|---|---|
|
Up/down totalizing is provided by a mode of the Extended counter where pulses are either added or subtracted on Channel A based on a direction input on Channel B. The counter can also be programmed so that counting by Channel A is inhibited by an input on Channel B. |
| Combining Two Totals | |
 |
A+B, A-B and A/B arithmetic functions are available with the Extended counter. A+B sums both totals, while A-B subtracts the outflow total from inflow total. The A/B ratio applied to total helps assure the proper mixing of components. Controller setup and monitoring of the mixing operation are facilitated by optional serial communications. RS485 allows a single data line to handle multiple controllers. |
| Up or Down Counting with Preset | |
 |
A single Laureate dual-channel counter will handle two repetitive fill operations by counting from zero up to a preset, or down from a preset to zero. A dual setpoint relay board is required. |
| Machine Rune Time and Utilization | |
 |
An easy way to measure the run time of machines is to count AC line cycles and scale the total to hours. To display machine utilization or duty cycle in percent, use the Extended counter. Connect Channel A to switched AC and Channel B to the AC line, and have the counter display the A/B ratio with a 100 multiplier. |
| Total and Rate Simultaneously | |
 |
The Extended version of the Laureate dual channel counter can display scaled rate or total for the same channel at the push of a button, and alarm both the rate and total. The Extended version can also do curve linearization, thereby extending the working range and accuracy of flow transducers. |
| System-level Capabilities | |
| The Laureate dual channel totalizer can independently scale, display and alarm two totals, and the totals plus alarm data can be transmitted via RS232 or RS485. The displayed totals can also be transmitted as an isolated 4-20 mA or 0-10V analog output. The Extended version can further display and transmit arithmetic combinations of the two totals. |  |
