The meter is with following features:l For circuit design, high-quality power modules are selected to be as power supply parts and highly stable and reliably imported devices are used as components of the meter. It can fully replace imported foreign meters of the same type. l Patent sonic-wave intelligent technology software can make intelligentized echo analysis. It needs neither debugging nor other special steps. This technology has functions of dynamic thinking and dynamic analysis. l Our sonic-wave intelligent patent technology greatly improves the meters precision, and the precision of liquid level is up to 0.3%, which is enough to resist various interference waves. l The meter is a non-contact one and does not directly contact liquid, so the fault rate is low. The meter can be installed in several different ways, and the user can make meter calibration according to the Manual. l The meters all input and output lines must be with such protection functions as lightning protection and short circuit prevention. 2、Technical targetsMeasuring range： 015m（Chosen based on actual measuring range）Blind area： 0.25m0.6mRanging accuracy： 0.3%（Standard condition）Ranging resolution： 1mmPressure： Less than four atmospheric pressureMeter display： With LCD to display liquid levels.Analog output： 420mADigital output： RS485, Agreement Modbus or customization agreementPower supply voltage： DC24V/AC220V, lightningproof device installed insideAmbient temperature： 20 60Protection grade： IP651 Ultrasonic Level Meter 4.3.4 Probe height（P04）P04 menus can be displayed probe height, can see whether the height can Meet the situation on the ground, Can also be used for Calibration of the liquid level. In accordance with the situation on the ground to change the value of the probe height4.3.5 Reaction rate is set（P05）（P05）Reaction rate is set “00 ”is the fastest; “01”is faster ; “02”is medium-speed; “03”is slow. 4.3.6 Blind spot Set（P06）Can change the instruments blind spot to accommodate to complex working conditions. For example, the protruding material impact on the instrument can be avoided near the transducers.4.3.7 Test 420mA （P09）(P09) Test 420mA current. 6 Ultrasonic Level Meter 【OK】：Confirmation key. Choose menu or confirm option and data. 4.2 Password directivePress key Mode, the password interface will appear: “0000”; press key 【】to change the first place into 1, and press key 【OK】to enter the interface of parameter setting menu.4.3 parameter setti4.3.1 Level Calibration（P01）Finished Meter installed, power-on. The LCD will show the level value, but the data are often inconsistent with the actual level, so it need level calibration.Level calibration steps are as follows: press 【Mode】and enter password then press 【OK】and enter the parameter setting menu. P01 is level calibration menu, Press OK button to P01 level calibration with (shift), and (numbers change) will be replaced by the actual level value of the number(as 2.100), Press OK button to confirm, then press Mode key to exit the parameter setting menu, LCD will be displayed at this time.4.3.2 Set 20mA（P02） Instrument Normal working hours press Mode key to enter the parameter setting menu, press choose menu P02, The second line corresponds to number shall be 20mA level, press OK key to set。For example: Range is 0 10 meter ultrasonic level gauge, the actual maximum level in the field is 6.5 meters, 6.5m can be set to 20mA, When the liquid level reaches 6.5 meters, the output current is 20mA. 20mA can also be set to 7.0 meters, then when the level reached 7.0 meters, the output current is 20mA4.3.3 Display mode settings（P03）Menu P03 can change the display mode, a total of three display modes to choose1. “00”Liquid level and relay status display2. “01” Display space distance3. “02”Display space distance and temperature , Press key to select the desired mode and then press the OK button to confirm.5 Ultrasonic Level Meter3、Installation of meter3.1 Meters overall sizeInstallation way: Open environment commonly used stent installation method, using a fixed flange own instrument.3.2 Meters wiring 2Ultrasonic Level Meter 3.3 The meaning of installation parametersAs shown, instruments transducers made after the wave hit the level reflected back to transducer, the transducer receives income calculated after the hair waves to waves of time, are measured from the L, meter installation height minus the measurement of TH the distance L will be the current level H. Meter range means the instrument can measure the distance, the installation should be less than a high degree of TH range. Instrument blind means measuring instruments in the vicinity of the transducer can not be measured in the region, the highest level with the transducer spacing should be greater than the blind, for example: blind spot for the 0.3m, the highest level with the transducer spacing must be greater than 0.3m.3.4 Instrumentation Principles1. The distance of transducer launching surface to the lowest level should be less than the purchase instrument range2. The distance of the transducer launching surface to the highest liquid level should be greater than the purchase of the blind instrument3. The launch surface of the transducer should be keep parallel to the liquid surface. 4. Transducer installation location should be as far as possible avoid these liquid surface fluctuations position that just under the inlet, outlet ,if It is impossible to avoid, 3 Ultrasonic Level Meterplease install guided-wave tube to aid in measuring.5. If the pool wall or tank wall is not smooth, meter installation location should at least more than 0.5m from the pool wall or tank wall. The specific distance from the pool wall or the tank wall determined according to the actual situation.6. If the distance of the transducer launching surface to the highest level is less than the blind area of the purchase instrument is required to install an extension tube, that diameter is greater than 200mm, and the length is 0.35m0.50m.3.6 Installation Notes1. The instrument used outdoors, it is best to install awning or the protecting housing, so as to avoid the LCD screen ageing affected by sunlight. 2. Wire, cable protection pipes, pay attention to sealing to prevent water, and prevent mice and other rodents Bite.3. Although the instrum
