We all know that the environment is becoming more and more important and news worthy every day, and we see more and more the effects man is having on the environment. As a result new tools have been developed to assist in monitoring this situation and some old tools have even been repurposed to help out. Among these older tools are flowmeters which are now being used not only to measure the impact we are having on our evironment, but helping to insure that new regulations are adhered to. Among the types of environmental flowmeters
common today is the use of open channel flowmeters to determine river and stream flows which have a potential of flooding, and laser flowmeters are being used to measure industrial outfalls to determine the total volume of liquids being discharged.
