Thermal Dispersion/Paddle Flow Level Switch - 2

PRODUCT INTRODUCTION OPERATING PRINCIPLE Thermal dispersion flow switches measure the velocity of a liquid inside a pipe or channel. The switch’s probe contains two key components – a heating sensor and temperature sensor. The heating sensor is positioned closest to the flowing liquid and provides a consistent heat. The temperature sensor measures the temperature emitted from the heating sensor. When liquid is flowing, there is a temperature difference between the two sensors. The temperature difference has an inverse relationship with the flow velocity (fast flowing liquids will result in...

INSTALLATION INSTALLATION 4. Screw tightly to avoid. Can be installed from various angles. For best sensitivity and response speed, please install using in the demonstrated in Fig. 4 5. Installing a filter upstream can decrease liquid impurities which can reduce wear and tear on the switch. 1. Use the water-proof gasket provided 2. The distance "a" should be 4 times larger than the switches’ screw diameter. (Fig. 1) 3. The pipe is bubble free for proper functioning. (Fig. 2) 4. For not-completely-filled pipes, install from the bottom. The liquid level needs to be higher than the probe...

PADDLE TYPE FLOW SWITCH PRINCIPLE SECTIONAL DRAWINGS Flow Switch can detect liquid movement in pipes. When the liquid is static or nonexistent, the spring is fully extended pulling the magnet downward and opening the switch. As flow occurs and the paddle is thrusted forward 20BC~30BC (or more) the paddle will push the magnet upward and actuate the switch (closing the circuit) The length of paddle can be adjusted to the pipe's diameter. 1.

FLOW CONTROL RANGE TABLE 1. The paddle length is dependent on the lowest paddle point to actuate the switch. Cut the pad- dle at appropriate pipe size mark or wherever 2. The paddle must be at a right angle to the direc- 3. The FLOW mark on the screw must be 4. Before installing the unit to a tee pipe, apply thread seal tape to the screw and then • Not recommended for 1" or smaller NPT plastic pipes. 1. The pressure and temperature ranges as shown in the catalog, must not be exceeded and also take the abrupt pressure and temperature into consid- 2. Large sudden changes in liquid temperature...
