Features
■Low transmitting power, weak energy, high sensitivity and small reverse Angle;
■The complete series of transducers can accurately complete the continuous non-contact measurement in different environments;
■Small blind area, high precision, and near the blind area can still guarantee the accuracy;
■The integration of transceiver and transceiver can accurately receive the weak echo signal and ensure the accuracy and reliability of the measurement;
■Safe and reliable, moisture-proof, anti-corrosion, suitable for different occasions, not affected by weather and other factors;
■All input and output lines are protected against lightning, overcurrent and overvoltage;
■Die-casting aluminum alloy waterproof, explosion-proof shell; protection grade IP67. Instrument explosion-proof grade reached Exd(ia)ia II BT4, can detect all flammable liquids except hydrogen H2, carbon disulfide CS2, acetylene C2H2 level;
■Low failure rate, easy installation, easy maintenance.
Product classification
■YI2000 Ultrasonic level gauge
YI2000 ultrasonic level gauge contains a number of self-developed patented technologies, and has a brand new signal processing technology, which is widely applicable to the level measurement of petroleum, chemical industry, water treatment, water conservancy, food, food and other industries. YI2000 has the features of safety, cleanliness, high precision, long life, stability and reliability, convenient installation and maintenance, and simple reading.
■YI4000 Ultrasonic liquid level difference meter
YI4000 type liquid level difference meter measures the distance between the surface of the transducer and the surface of the object under test according to echo ranging principle.Two ultrasonic transducers measure the level height of the upstream and downstream respectively. The meter shows two levels and the level difference. Two channels of 4~20mA can be arbitrarily set as the level or the level difference output.
■YI3000 Ultrasonic open channel flowmeter
The YI3000 ultrasonic open channel Flowmeter uses ultrasonic wave to measure the water level height in the open channel Weir trough in a non-contact manner and then automatically converts the corresponding flow value by the microprocessor. The liquid crystal displays the instantaneous flow and accumulative flow while the liquid level shows the warning indication of the liquid level and the upper and lower line. The instrument uses EEPROM digital memory to ensure that the data in the instrument will not be lost after power failure. The instrument is also equipped with explosion-proof probe specially designed for petroleum and chemical departments to meet the measurement requirements of sewage flow in explosion-proof areas of petroleum and chemical industries (explosion-proof grade EXiaIIBT4), especially suitable for Flow measurement of oily wastewater.
YI3000 ultrasonic open channel flow can also be used as a continuous monitoring and accumulative flow of sewage in open channel. Non-contact liquid level meter can be used for water conservancy, hydropower, environmental protection and other industrial and agricultural open channel flow measurement.
