An example of an application that would require such materials would be if a manufacturer of metal plating and metal finishing lines required continuous level measurement of their chromic acid tanks. Stainless Steel would rapidly corrode in chromic acid, which is why one would have the option to go with a PVDF float, which is a material with ...
A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float. Another common type is a float that raises a rod to actuate a microswitch ...
The choice of float material is also influenced by temperature-induced changes in specific gravity and viscosity – changes that directly affect buoyancy. [5] Float-type sensors can be designed so that a shield protects the float itself from turbulence and wave motion. Float sensors operate well in a wide variety of liquids, including corrosives.
Originally developed in 1958 by inventor and cleaning product pioneer, Harry O’Hare, Ty-D-Bol in its original form is a blue liquid cleanser/disinfectant for the toilet bowl. Other variants, such as a solid tablet in a water-soluble wrapper, to be placed in the toilet's water tank, were introduced later. [3]
It consists of a valve connected to a hollow, sealed float by means of a lever mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises ...
Since fuel can be present in the bilge, electric bilge pumps are designed to not cause sparks. Electric bilge pumps are often fitted with float switches which turn on the pump when the bilge fills to a set level. Since bilge pumps can fail, use of a backup pump is often advised. The primary pump is normally located at the lowest point of the ...

An automated tank cleaning machine is a machine used to clean cargo, process, underground storage tanks and similar equipment such as those found in tank trucks, railroad cars, barges, oil tankers, food and beverage manufacturing facilities, chemical processing plants, ethanol ...
A Single-Pole, Single-Throw (SPST) mercury switch on millimetre graph paper, device length approximately 1.5 cm Another mercury switch design. A mercury switch is an electrical switch that opens and closes a circuit when a small amount of the liquid metal mercury connects metal electrodes to close the circuit. There are several different basic ...
