Ultrasonic wave level sensor characteristics:in petrochemical engineering and architecture field,common level sensor include rotation coding sensor、piezoelectric sensor、non-contact sensor,its distinguishability from millimetre to centimetre,measurement range from several centimetres to several meters .Except for magnetic float contaction point sensor,other sensors suitable for the wide application places.Generally,pressure type and ultrasonic sensor equip with transmitter,turns level signal into standard current signal(4~20mA).Rotation coding sensor divided into mechnical type and photoelectric type,this kind of sensor often output parallel binary code、serial binary code or pulse signal.Except for intergregated sensor(pressure or ultrasonic wave),without display on-site and digital communication function.In these sensors,ultrasonic wave level sensor is uncontaction measurement instrument,in measurement process,without any parts that contacted with tested mediun,so whether liquid level is move、wave or with flotage and chemical reaction,in can be used,and have no relationship with tested medium pressure、temureperat、density、corrosicity,widely using range,can used to industrial raw materials、river level measurement.Compared with various measurement methods,ultrasonic wave measurement has beyond comparison advantages,low cost,stable performance,high accuracy,energy converter life is long,easy to use,is ideal instrument of non-contaction measurement.
One.Ultrasonic wave level sensor characteristic:
1.High measurement accuracy.
2.Short reaction time,can easy to realize non-hysteretic real-time measurement.
3.Non-contaction measurement,stable performance,strong adaptability to level physicochemical property,not fear acid-base ect strong corrosive liquid.Intelligent ultrasonic wave level sensor is based on ultrasonic wave level sensor,use microprocessor as control core,with traditional ultrasonic.
