Innovative ultrasonic level measurements...

SmartScan® 25 is a family of ultrasonic
continuous level measurement instruments
that directly address the most pressing
challenges in the field. Attempts to
compensate for changing temperature
variations with tanks have not been
successful. Sound waves remain
inconsistent, and signal transmission and
reception are unsynchronized. Even
sophisticated and expensive devices do not
achieve the repeatability and linearity vital
for accurate measurement. When translated
into dollars and cents, the price of these
uncertainties is too high.

 Advantages

• Installation in high process tanks, large storage vessels, and extended range applications
• Self-adjustment to virtually all types of conditions
• Full compensation in virtually all environments: vapors, gases, temperature variations, wind, etc. providing highest accuracy even under extremely harsh conditions
• 0.25% accuracy of measuring range
• For ranges of up to 40 meters (131 ft)
• Resolution: 1 mm (0.04 inch)
• Variety of sensors for each application
• No calibration or maintenance required
• Radar-like performance at an affordable price

 Features

• 4-wire low voltage device
• Customized graphic LCD display
• Coated Aluminum (ECTFE-Halar), PP/PVDF sensor
• Temperature: -40° to 80° C ( -40° to 176° F)
• Interface/Communication: RS232, RS485, Modbus
• Relays: 5 SPDT relays (independent On/Off programming)
• Integrating 4 modules:
• Standing wave control transmits a fixed pulse and frequency at constant voltage, enabling the instrument to receive a similarly controlled oscillation where each wave is identifiable. By measuring energy loss as a function of the speed of sound, SmartScan® 25 can cope with even the most difficult environments.
• Dynamic and static echo control features an innovative algorithm enabling automatic (dynamic) identification, learning and storage in memory of disturbances and noises without human intervention.
• Temperature control rapidly compensates for changes in temperature and corrects the reading accordingly.
• Gain control's special algorithm enables full monitoring of signal amplification received from the sensor, and ensures an accurate and reliable reading even in the presence of gases or vapors.
