PVC Tank Liner Tue, 13 Jul 2021 00:00:00 +0530 Tank liners prevent the material stored in the tank to keep contact with the tank surface thereby ensuring the stored material to remain contamination free. It does so in the following ways:   Improves Impermeability : Most of the storage tanks are filled with some sort of liquid, water in general. Over time this liquid finds its way out of these structure walls. Concrete can absorb moisture and metal can rust, therefore a liner ensure that there are not any leaks present. Chemical Integrity : Liquids when stored in a storage tank without liner can react with the surface of the tanks and get contaminated. A liner ensures that there is no direct connection connection between the stored liquid and the tank. Flow Switch Tue, 13 Jul 2021 00:00:00 +0530 A flow switch is a mechanical instrument that is used to control the flow of air, steam or liquid. Flow switches work by sending trip signals to another device (a pump for example) within the system, telling it to shut off or to turn on, which will further protect it from damage and for cooling circuit protection. Flow switches determine if flow is above or below a certain rate, known as a set point. The set point can either be adjustable or fixed, depending on the specification of the individual instrument. When the set point is reached, the response is often the actuation of an electric circuit. Once tripped, the flow switch stays in its new state until the fall falls below the set point.
