How to achieve the opening and closing of a material valve for level control in the simplest way possible
Thread Content
Is it possible to make the solenoid valve on the feed line open automatically when the liquid level drops below a certain threshold, without using a controller?； When the level exceeds this value, the solenoid valve closes automatically again.
Hehehe, my dear, if we don’t use a level switch or a level controller, then where do the signals for opening and closing the valves come from? . .
The on/off switches of the solenoid valve can be controlled using the high/low level alarm contacts and relays of the level gauge.
Two level switches, along with a relay, can achieve this
Use liquid level alarm switches such as float switches directly, along with relays
Is it a dual float ball? One high liquid level control and one low liquid level control?
For this purpose, an intelligent level switch is the perfect solution – it sends an alarm signal when the liquid level reaches 1 meter, and stops sending the alarm signal when the level reaches 5 meters. Refer to SC829 for details. .
Two level switches, together with a relay, can be used to ensure that the solenoid valve on the feed line opens automatically when the liquid level drops below a certain threshold； When the level is above this value, the solenoid valve closes automatically again
Two level switches (high alarm, low alarm)； Floats, tuning forks, ultrasonic waves, etc.) can directly interlock switch valves. It is also possible to use a level gauge connected to a digital display with alarm function, along with control valves
Yes, there are some; we have them here
