The Laurel Laureate process meter & flow totalizer is a highly accurate, 6-digit digital panel meter for displaying rate or total at the push of a button. The Laureate process meter & flow totalizer utilizes a voltage-to-frequency signal conditioner board which can be scaled to display rate or totalized rate to six digits for 0-1 mA, 4-20 mA or 0-10V analog process signals.
The Laureate process meter & flow totalizer is supplied with a standard main board to calculate rate, square root of rate, or totalized rate from transducers with a DC output. With the optional extended board, those functions are available as well as custom curve linearization, batch control operation, 1/rate (time). Square root extraction is selectable and can be applied to rate or total. This makes the Laureate process meter & flow totalizer ideal for use with differential pressure flow meters, which have a squared output. Totalized volume is based on linearized rate.
The Laurel Laureate process meter & flow totalizer includes a 6-digit high resolution display. The display of rate or total may be scaled to ±999,999. The two least-significant digits may be set to display zero with rounding or be active digits. Noise in rate readings can be reduced by selecting a longer gate time. In addition, an adaptive digital filter can reduce variations due to noise while rapidly responding to actual changes in signal level. The Laureate has one of the highest accuracies of any digital panel meters: ±0.005% of span ±1 count.
Optional plug-in boards for communications and control include Ethernet and other serial communication boards, dual or quad relay boards, and single or dual isolated analog output boards. Laureates may be powered from 85-264 Vac or optionally from 12-32 Vac or 10-48 Vdc. The display is available with red or green LEDs. The 1/8 DIN case meets NEMA 4X (IP65) specifications from the front when panel mounted.
