In the realm of Environmental & Water Treatment, accurate flow measurement is crucial for process control, efficiency, and regulatory compliance. One essential tool employed for this purpose is the SK flowmeter, a term often used to refer to variable area flowmeters, particularly those manufactured by McCrometer, Inc. These devices offer a unique combination of accuracy, reliability, and versatility, making them indispensable in diverse applications.
What are Variable Area Flowmeters?
Variable area flowmeters, also known as rotameters, operate on the principle of differential pressure. They consist of a tapered tube with a float inside. As the fluid flows through the tube, it exerts a force on the float, causing it to rise. The higher the flow rate, the higher the float will rise in the tube. A scale calibrated against the float's position indicates the flow rate.

Task:
A wastewater treatment plant uses an SK flowmeter to monitor the outflow of treated water. The flowmeter indicates a float position of 35 cm on a scale calibrated from 0 to 50 cm. The flow rate corresponding to 50 cm is 1000 m³/h. Calculate the current outflow rate of the treated water.
The flow rate is directly proportional to the float position. Therefore, we can set up a proportion:
Flow rate / Float position = Constant
Let 'x' be the current flow rate. We can write:
x / 35 cm = 1000 m³/h / 50 cm
Solving for 'x', we get:
x = (35 cm * 1000 m³/h) / 50 cm = 700 m³/h
Therefore, the current outflow rate of the treated water is 700 m³/h.
