Description
The Laurel Laureate VF is a 6-digit panel meter that displays the rate or the running total of a 0–1 mA, 4–20 mA or 0–10 V process signal with ±0.005% of span accuracy. Square-root extraction makes it suitable for differential-pressure flow transmitters, and a built-in isolated 5, 10 or 24 V DC supply can power the transmitter.
The Extended version adds batch control, time-from-rate display and custom curve linearization (up to 180 points). Options include relays, an isolated analog output and Ethernet, USB or RS485 Modbus communication. It fits a 1/8 DIN panel cut-out, NEMA 4X from the front.
Argonmark Ltd supplies Laurel Electronics instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
