fixierbar Ultraschallgerät

fixable ultrasonic instrument Type Portable Type Handset Type Fixed Type Measuring Principle When the ultrasonic beam is transmitting in the liquid,its transmit time is proportional to the liquid flow. Application for continuously measuring the flow of most clear,single and pure liquid which do not have large consistence suspended matter or bubbles. Linearity Better than 0.5% Accuracy Better than 1.0% Repeatability Better than 0.2% Velocity Range 0±32m/s Pipe Materials Steelstainless steelcast ironPVCcement pipe and other pipes whose materials are close . Liner are Optionalthere can not be the interspace between the liner and the pipe exine) Pipe Size S model sensor(with magnetism:50-100mm) M model sensor(with magnetism: 50-700mm) L model sensor(no magnetism:300-6000mm) Sensor Installation Method Clamp-on Measured Liquid watersea wateracid and alkalifood oil gascoal oildiesel oilpetroleumalcoholbeer etc.these single and pure liquid which can transmit ultrasonic beam Ambient Temperature Convertor - 10 - 70, Fluid Temperature Normal sensor-30 +80 High temperature sensor-30 +160only for Smodel and Mmodel,no magnetism Display 2 lines display the instantaneous flow,totalize flow and signal state 2×10LCD display.Display the instantaneous flow and the positive negative net totalizer flow and velocity etc. Signal Input No signal input No signal input 4-20mA analog signal input,accuracy 0.1%,can imput pressure,liquid level,temperature and so on. PT100 platinum resistor. Signal Output RS485 4-20mA or 0-20mA current signal output OCT output (pulse width 6 1000ms,factory setting is 200ms) relay can put out positive,negative,net accumulative pulse and the alarm signal.
