Water, Air, Gas and Oil

You can get low cost rotameters for measuring the flow of water, oil or air. These cost-effective solutions use a tapered tube and a small object to indicate the flow rate when the drag is in equilibrium with the weight of the float. These products provide excellent stability and process consistency by allowing you to easily repeat measurements. We can definitely work with you to make sure you put together the right order for your specific application. Request a quote or speak with one of our engineers to learn more about our selection and find the perfect rotameters for you. We have worked with a wide variety of clients and can ship to anywhere in the world. We will make sure that your order arrives on time and fits your budget. Contact us today!
