The Laureate™ 1/8 DIN Panel Meters for dual-channel frequency, rate and period meter
is a standard operating mode of the Laureate counter with the FR signal conditioner board. It can display frequency from 0.005 Hz to 1 MHz, rate in engineering units, and period (inverse of frequency). The normal displayed value can range up to 999,999 counts. Above that level, the display will flash and go into four-digit XXXXEX scientific notation. Each channel (A or B) may be independently scaled for frequency, rate or period. The displayed channel is selected via a front panel pushbutton. Examples of applications are the accurate display of AC line frequency, RPM, speed from proximity switch inputs, and flow from turbine flow meter inputs.- Fast, high resolution measurements. The Laureate counter determines frequency by timing an integral number of periods over a specified gate time, and then taking the inverse of period. Rate is obtained by multiplying the input by a scale factor. The inverse period approach allows greater accuracy and faster update times than conventional meters which count signal pulses over a time interval. AC line frequency may be accurately measured to 50.0000 or 60.0000 Hz in a few line cycles. 1000 Hz signals may be measured to 0.01 Hz resolution at up to 25 readings per second. Fast response is ideal for alarm and control applications.
- For noise reduction, a count by 10 or 100 feature with rounding is selectable. Variations in the displayed reading can also be reduced by selecting a longer gate time. An adaptive digital filter is selectable to reduce variations due to noise while rapidly responding to actual changes in the signal.
Laureate 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 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 Counter Version 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 panel meters 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. A built-in (isolated) 5, 10, 12, or 24 Vdc excitation supply can power proximity switches and other sensors, thus eliminating the need for an external power supply.
- 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.

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.
