Intelligent Flow Switch (MFM500A)
Introduction
MFM500A Flow Switch is an intelligent thermal diffusion principle-based flow monitoring sensor. It can ensure measurement accuracy in the case of water temperature change and is available for real-time monitoring of pipe water flow.
With self-luminous OLED screen, it allows switchable display between the progress bar and digital display numbers. MFM500A supports quick action point set, also it has display inversion function that enables installation in any direction, and no need for frequent adjustment and maintenance.
It can be applied for operation protection of large equipment in fields such as power generation, metallurgy, steel, paper, boilers etc.
Features:
·Optional power supply 24VDC or 220VAC
·OLED screen, switchable display between the progress bar and digital display
·All stainless steel housing, IP67 protection
·Temperature compensation
·2-way PNP ¦ 2-way NPN ¦ 1 relay output are optional
·No moving parts, maintenance-free
·Switch output, control point setting continuously on panel
·Compact size, support inverted display
·Mounting joint can be equipped with different interfaces for a variety of pipe diameters requirement
