When a North American bulk liquid transportation company needed reliable level measurement of their tanker trailers, they turned to Flowline. With a range of services from chemical delivery to pick up and remediation, they have diverse applications and requirements. This particular tanker is Teflon® lined and used to pick up acid waste including hydrochloric and nitric, which are highly corrosive, vaporous and foaming when agitated. The company has successfully deployed Flowline ultrasonic sensors in other applications, but not here, due to the presence of vapor and foam. For this reason, Flowline suggested the use of our pulse radar sensors which are unaffected by such conditions. The result is reliable acid waste level measurement.
