Liquid Flow Meters and Switches

Water flow meters are basically the tools which are used to measure the consumption of water. It measures the total amount of water used by any source through different methods. These meters are designated in specific points to identify leakages of water. Although modern technology has led to the invention of various types of flow meters, two of the most commonly used meters include the positive displacement meter and the velocity meter. There are devices which combine the features of both these meters are known as the compound meters. These devices particularly use a valve mechanism which directs the flow of water into both these meters so that it is easy to obtain readings from both the devices. Types of Flow Meters: Positive Displacement Meters: These meters include a small chamber which holds a measured volume of water. The flow of water is measured and compared to the previously held volume of liquid. The flow rate of the liquid is calculated by measuring the

8000 Series Liquid Flow Meters Before drawing conclusions on the best flow meter for industrial use, you should first understand what they are and how they work. The turbine flow meter consists of rotor blades placed at an angle on a shaft. The fluid passing through the blades causes them to turn the rotor shaft. The rotation of the shaft is sensed by a mechanical reader. As for the blades, a magnetic reader detects the movements through magnetic pulses. Movement of the blades and the rotor is proportional to that of the liquid.  This is ideal for gases and liquids. Special considerations are taken for non-lubricating fluids. The blades are usually greased if the meter is intended to measure such a fluid. In measuring the transmission of natural gas, the blades can only withstand temperatures of up to 60 degrees Celsius. A turbine flow meter is ideal for corrosive as well as clean liquids. These include chemicals, petroleum and water. The pipe size should not exceed a diame
