From Madison Company
The key to ultrasonic liquid detection is to keep the beam perpendicular to the liquid level and away from structures like tank walls, internal ladders, and impellers. If ordering a USR Series model with a tri clamp, remember that a ferrule has to be welded to the vessel's top in a way that the perpendicular relationship to the liquid would be maintained. The ferrule needs to be as short as possible to avoid the danger of picking up false targets in what could be considered an effectively long pipe. Products & Services
Impellers are rotating devices that force liquids, gases and vapors in a desired direction. They are widely used in pumping, blowing, and mixing applications.
Volumetric liquid flow switches are devices with a switch output used for measuring the flow or quantity of a moving fluid in terms of a unit of volume per unit time, such as liters per minute.
Ultrasonic flow meters use sound frequencies to determine flow rates. They do not work well with liquids with suspended solids or air gaps.
Electromagnetic flow meters operate on Faraday's law of electromagnetic induction, which states that a voltage is induced when a conductor moves through a magnetic field.
Ladders are devices that workers use to step up or gain access to elevated surfaces.
