Measuring the flowrate and taking water samples of industrial wastewater presents significant, unique challenges. Accuracy and defendable data is imperative, whether the data is for billing confirmation, plant management, or regulatory compliance. That said, the effluent commonly contains solids, is chemically corrosive and may be at higher temperatures. Such instances make a submerged flowmeter impractical if not impossible to use. In some cases, even a flume is untenable due to build-up or blockages that create a constant need for costly maintenance and safety concerns.

So, what is the right choice for flowrate monitoring? A variety of sensor technologies are available and choosing the right one can make or break you. During this presentation I will describe the differences and benefits between the sensor technologies and provide insight on which solution is best for you.

Water samplers combined with a flowmeter will capture the volume of flow in your collection system and take samples during specific discharge events. Water samplers can automatically isolate samples into specific bottles. Samples can be triggered on multiple conditions such as high flow rate, pH limits and temperature.
