PLATO MONITOR

Application

PLATO MONITOR is a variant of SONATEC and allows measuring original gravity of beer in the manufacturing process. Typically, original gravity is determined during beer filtration and in front of the filler.

Description

PLATO MONITOR is a special version of SONATEC and continuously measures the speed of sound through the product. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintenance-free. For sound velocity measurement a sound pulse is created by a piezo-element in a sonic transmitter. It moves perpendicular to the product flow towards a sonic receiver where it is detected. Since the distance between transmitter and receiver is known, the sound velocity can easily be calculated by measuring the travel time of the sonic signal. As a specific property of each liquid, the correlation between concentration and sound velocity can be described by a mathematical polynomial. With decades of experience and our own laboratory facilities, Centec know the polynomials for a large number of products. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt1000 sensor.
