working principle:
Online installation, mechanical flow switch for monitoring liquid or gaseous media. Rugged plastic or anodized aluminum housing is available.
Features:
Minimal pressure loss, good repeatability, strong anti-fouling ability, complete separation of mechanical parts from electronic parts, suitable for pipeline flow monitoring or control. The piston stroke of 3 times the original FE20 makes the setting accuracy more precise. With the switch setting scale, the user does not have to set it on site. LED display switch status, multi-channel switch output is available.
Technical Parameters:
Accuracy: ±2% of total range
Hysteresis: depending on the switch point, minimum 0.6L/Min
Setting the scale: Mounting position, medium and temperature changes have a slight effect on the switch value
LED display: DC power LED display switch status, AC no LED display
Output: Reed switch, capacity 24VDC/250VAC, 100mA
