FP4W

FP4W is a modern, versatile and precise flow meter with internal data logging. Equipped with two analogue inputs (RTD, 4-20mA, voltage or resistive output transducers) and two PULS inputs (frequency measurement, pulse counting, binary signal tracking and recording), can measure flow and other values, such as temperature and humidity. In addition FP4 has two math channels and two totalizers assigned to each of the six available channels. All this in a device with a 4-inch touch screen.
