It adopts ARM processing core and combines with high quality sensors and dedicated circuit. With temperature-compensation and calibration, it can ensure measurement accuracy in the case of water temperature change. It is available for real-time monitoring of pipe water flow. It can be used for cooling or lubrication system flow monitoring to realize pre-warning and protection for critical equipment when there is flow fault. It uses fully enclosed design, stainless steel construction to adapt to a variety of application environment. It is with overvoltage, over-current and reverse polarity protection function. 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. Specification Measure Range:1cm/s~150cm/s (water); Optimal Range: 3cm/s～100cm/s (water) Output Function: NO, NC(optional) Relay Characters: Transistors Characters: Switch Voltage Drop: ≤ 1.5V Initial Time: 2s~15s, 8s(typ.) http://www.microsensor.cn Add: No.18,Yingda Road Baoji,P.R.China, Tel: +86 917 3600739/36
