The principle and method of controlling the float valve to control water by frequency converter

First, the float ball level controller works based on the principle of buoyancy. The float system is designed to respond to changes in liquid level. When the liquid level rises, the float also rises accordingly, and when the level drops, the float follows suit.

At a predetermined level, the float will come into contact with a travel switch or another electronic sensor. This triggers an electrical signal that is sent to the control unit. Once the signal is received, the control system can activate or deactivate the pump, allowing for automatic water level management.

This type of system is commonly used in tanks, reservoirs, and other liquid storage systems where maintaining a specific water level is essential. It ensures efficient operation and prevents overflows or dry runs.

Second, the inverter controls the float ball valve to regulate water flow

The float switch acts as a level detection device. When the water level drops below a set point, the float switch sends a signal to start the inverter, which in turn activates the pump to refill the tank. Conversely, when the water level reaches a higher threshold, the inverter stops, shutting down the pump.

In this context, the inverter functions like a soft starter, allowing for smooth motor operation. It’s important to connect the float switch contacts to the inverter's enable input to ensure proper control. This setup helps reduce mechanical stress on the pump and improves overall system efficiency.

Using a combination of float switches and inverters provides a reliable and energy-efficient solution for water level control in various industrial and residential applications.
