| AC Line Frequency |
 |
Laureate frequency meters and transmitters accept line voltages up to 250 Vac and output line frequency to 6-digit accuracy (50.0000 or 60.0000) in a few line cycles. Fast low frequency response is achieved by timing the period and taking its inverse. |
| RPM and Speed |
 |
Laureate frequency meters and transmitters can sense low-level signals from magnetic pickups or the NPN or PNP transistor output of active sensors. These can be powered directly by the meter or transmitter. Output in RPM or units of speed is achieved by mathematical scaling. |
| Flow Rate and Simultaneous Total |
 |
Laureate frequency meters andtransmitters are compatible with all flow meters which generate pulses at a frequency proportional to flow rate. The Extended version can display scaled rate or total for the same input at the push of a button, and alarm from both the rate and total. |
| Combining Two Rates |
 |
Extended Laureate frequency meters and transmitters offer A+B, A-B and A/B arithmetic functions. A+B allows two input flows to be summed for total flow, while A-B allows outflow to be subtracted from inflow for net flow. Flow ratios aid in the proper mixing of ingredients. |
| Custom Curve Linearization |
 |
Extended Laureate frequency meters and transmitters can linearize the output turbine flow meters, which tend to be nonlinear on the low end. Linearizing improves the dynamic range and accuracy of turbine flow meters. |
| System-level Capabilities |
| Laureate dual-channel rate meters and transmitters can independently scale, display and alarm two pulse input channels. All signal or alarm data can further be transmitted via RS-232 or RS-485, including peak readings and arithmetic combinations of the two rates. |
