Produced in PVC, equipped with a device for liquid level checking. When liquids go over the present limit it makes a float go up and a hummer work. It is possible to install a warning light and an automatic electric exhaust-valve on request. That device can work even in the opposite way, that is setting a minimum level under which the device begins humming.
