Kenco SmartSonic Acoustic Wave Level Transmitter

SmartSonic Acoustic Wave Level Transmitters utilize a breakthrough, patented technology to provide accurate measurement even under harsh conditions. SmartSonic transmitters provide a unique combination of strength, performance and value.

Acoustic Wave Transmitters are suitable for a wide range of level and open channel flow applications. Since this technology does not contact the process media, measuring thick, sticky, and high viscosity fluids is simple. Built-in temperature compensation insures an accurate measurement in applications with varying temperatures.

KENCO Acoustic Wave Transmitters are CSA (SmartSonic Integral) Certified and FM (SmartSonic Remote) Approved for use in hazardous areas. This makes them the perfect choice in any Chemical, Petrochemical and Petroleum applications.

Principle Of Operation:
SmartSonic Transmitters consist of two main components:

• The Electronics
• The Sensor (Transducer)

The transducer contains a piezoelectric crystal that converts an electrical signal into acoustic (sound) waves. These acoustic waves are directed through the air toward the process media surface. They are then reflected off of this surface and returned tot eh transducer. The piezoelectric crystal then converts the received waves into an electrical signal.

The time difference between the transmitted wave and the received wave is proportional to the distance from the face of the transducer to the process media surface. The distance is used by the electronics to calculate level or open channel flow in the units selected by the operator.

Features:

• 5° Beam Angle focuses the Acoustic Wave on process media

SMARTSONIC INTEGRAL

The SmartSonic Integral is a 24Vdc, two-wire, loop powered transmitter capable of ranges up to 49.4 feet. The electronics and sensor are contained in a simple, integral package, making installation a breeze.

The SmartSonic Integral Transmitter has the ability to locate and store up to six interfering signals (false echoes) in memory. This allows the transmitter to ignore obstructions such as a ladder, man-way entry, side-mounted sensors, etc.

Each reading is stored as a false echo, until a reading is achieved that indicates the real echo. This program must be run with the vessel empty. If more than six falso echoes are recorded before the real echo, the transmitter must be relocated.
