| Flow from a Differential Pressure Transducer |
 |
An ideal application for the Standard Laureate VF meter: readout of flow based on the 4-20 mA analog signal from a differential pressure transducer. Options include dual relays for alarm or control, isolated analog output to turn the meter into a transmitter, and RS232/485 data communications.s |
| Up- or Down-Counting Batch Controller |
 |
An ideal application for the Extended Laureate VF meter: up- or down-counting batch controller. The dual-relay card is required. One relay is dedicated to batch control, the other relay is available to alarm the rate or total. The signal input can be linear or nonlinear. The display can be toggled between rate and total. |
| Volume of an Irregularly-Shaped Tank |
 |
The Extended Laureate VF meter can linearize analog signals for display and alarm using custom curve linearization with multiple nonlinear segments. As illustrated, tank level is measured by an ultrasound detector, which transmits a 4-20 mA signal. This signal is then converted to a highly accurate volume reading. Linearized readings can also be totalized. |
| Process Time from an Analog Rate Signal |
 |
A unique application of the Extended Laureate VF meter is displaying process time based on the 4-20 mA or 0-10 V signal from a rate meter. In this example, a tachometer transmits the speed of a conveyer belt through an oven. The meter displays baking time in the oven using the mathematical relationship time = distance / speed. |
