SmartMeasurment - Ultrasonic Flow Meter

The SMC Alsonic DSPPL series is a portable transit-time ultrasonic flowmeter with clamp-on transducers for non-invasive liquid measurement. This
device uses patented "fine time measurement technology", making use of ultrasonic beams that can measure at pico-seconds time intervals. This rapid array
of measurements enables accurate, drift-free flow rate measurement in liquids that contain a second phase of entrained solids or gas bubbles. The use of DSP technology
enables "Cross Correlation" of ideal signals to cancel extraneous noise signals, and create a three-dimensional cross section of the velocity distribution
profile of the medium flowing through the pipe. DSP technology also enables the use of "FFT (Fast Fourier Transforms)" in order to generate the two signals at the same frequency; thereby increasing the signal-to-noise ratio for accurate, drift-free flow measurement in liquids.

Alsonic Building Automation - Energy meters employ transit-time ultrasonic flow
measuring technology combined with two integrated PT1000 RTD temperature sensors for calculating both
total and instantaneous energy consumption. These in-line style flow sensors are available for line sizes
ranging from ½" to 12". The Alsonic BA Energy meter may be used to provide highly accurate thermal
energy measurement in chilled water, hot water and condenser water systems. Our microprocessor based,
field programmable electronics provide local indication of energy, flow and temperature data via an
alphanumeric LCD display. An isolated solid state dry contact is provided for indication of pre-programed
totals or alarm conditions. Optional analog outputs and network communications are also available.
