1.4 LaureateTM Rate Meter & Totalizer with Functions A+B, AB, AxB, A/B, A/B-1:

Arithmetic functions A+B, A-B, AxB, A/B, A/B-1 applied to channels A & B are Laureates capabilities with expansion counter main board and channel signal conditioning board FR pair. These functions can apply to ratios or totals after scaling to engineering units. The following are examples of applications:

  • Add the two streams (A+B) to get the total flow or total volume.
  • Subtract the two flows (A-B) for the actual flow rate or actual volume.
  • Take the ratio of two flow rates (A/B) to mix chemicals.
  • Take the RPM ratio or belt speed (A/B) to synchronize moving machinery.
  • Subtract 1 from the ratio (A/B-1) to control the elongation of material compressed by rollers (drawn).

Used for controlling the mixing ratio of two liquids, calculating net liquid inflow and outflow, controlling film coating thickness, synchronizing two conveyor lines and measuring elongation.

1. 8 Laureate Laureate Duty Cycle & Pulse Width Modulation (PWM) Meter:

Duty cycle is a measure of ON or OFF time as a percentage of total time. The duty cycle is determined by averaging a number of integrals of time intervals over a selectable gate time from 10 ms to 199.99 seconds. Applications for duty cycle and pulse width modulation (PWM), applications in monitoring laser speed and performance.

1. 10 MAGNA Series Large Digit Displays:

Viewing distances of up to 320 feet (100 m) are achieved with 8 digits. The general rule is that the viewing distance in feet is 40 times the digit height in inches or in metric terms, the viewing distance in meters is the digit height in millimeters divided by 2.

Indoor or outdoor viewing: MAGNA series displays with normal brightness LEDs can be read on the machine or on the factory floor. The display has outdoor brightness LEDs that can be read on industrial yards, parking lots or roads, for example to show vehicle loads. Optional heater allows outdoor operation in winter in cold climates. Available mounting options are panel mount, wall mount, and wall mount. Environmental protection standards according to IP65 standards (NEMA-4X).
