PNP Outut 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.
Applications:
1. Power generation,
2. Metallurgy
3. Steel
4. Paper
5. Boilers etc.
Features:
·Optional power supply 24VDC or 220VAC
