DI.MPU 01

“TRANSIT TIME” FLOW METER

THE DSP TECHNOLOGY (DIGITAL SIGNAL PROCESSING) ENSURE A LOW SENSIBILITY OF THE INSTRUMENT AGAINST POTENTIAL TRANSIENT FACTORS. THE SIZE OF THE PIPE MAY VARY 20 ÷ 4000 MM (USING DIFFERENT TRANSDUCERS). SINCE THE TRANSDUCERS ARE APPLIED EXTERNALLY TO THE TUBE, NOT IN CONTACT WITH THE LIQUID AND HAVE NO MOVING PARTS, THE TRANSMITTER WILL NOT BE DAMAGED BY WEAR, BY FOULING OR PRESSURE
All CONFIGURATION USER-ENTERED VALUES are saved inEE PROM, PW protected
The Transmitter is EQUIPPED WITH A CLOCK TO STORE THE MEASURE DETECTION DATE AND TIME operated by battery
IN CASE OF POWER FAILURE will be necessary TO RE-SET THE LOST. IN CASE OF INCORRECT SETTING OF THE TOTALIZER, THE OTHER FUNCTIONS ARE NOT COMPROMISED
Is composed by a DIGITAL CONVERTER AND 2 CLAMP-ON OR INSERTION ULTRASONIC TRANSDUCERS
