measures flow by using two internal resistors to track heat loss. As liquid or gas passes by, it cools a heated resistor, and the sensor compares it to a cold reference resistor to calculate the flow rate. It is ideal for monitoring flow in gas, liquid, water, and oil systems, while effectively protecting pumps from running dry.

Features:

• It has a compact design with no moving parts and requires zero maintenance.
• It is easy to install, and one single model fits many different pipe sizes.
• The switch settings are fully adjustable with almost zero pressure loss.
• Bright LEDs clearly show the flow trend and the current switch status.
