UL-805 Heavy hammer level gauge (servo level measuring instrument)Detailed product description：

Overview
The UL-805 heavy hammer level gauge (servo level measuring instrument) is a new type of level measuring device developed by our factory. This new level measuring instrument can not only accurately measure oil level and water level, but also accurately measure the level of materials such as sewage, mud, powder, particles, etc. Especially for the measurement of levels such as sewage and mud, it has been widely recognized and praised by users. The UL-805 heavy hammer level gauge (servo level measuring instrument) is an intermittent direct measuring instrument, which is equivalent to a robot monitoring on site in real-time, replacing manual measurement. The UL-805 servo level measuring instrument can not only display and control the level on site, but also display and control it in the control room.

working principle
The working principle is probe type. The servo motor drives the probe to detect downwards from the starting position (top). When the probe touches the level of weight loss, the weight loss sensor sends an electrical signal, triggers the counter and controller, displays the level height, and the motor drives the probe back to the starting position, waiting for the next command to detect.
The controller can display the height of the object level, set upper and lower limits, and remotely transmit the object level signal to the control room and accept remote control signals, while also setting the detection cycle.

Main Features
1. It is not affected by the mist generated by the on-site medium or the liquid level fluctuation generated during mixing, and has strong adaptability to non-contact ultrasonic and radar wave level gauges.
2. It is not affected by impurities, conductivity, grounding, or liquid level fluctuations, and has stronger adaptability than radio frequency admittance and magnetostriction.
3. Suitable for sewage, dirty oil, and molten media, not afraid of blockage, and has stronger adaptability than input type and float level gauges.
4. It is not affected by the measurement depth and can measure up to 45M.
5. It can measure the height of different particles such as coal powder, grain, and powder ash.
6. The measuring component is made of stainless steel, which is not afraid of medium corrosion.
7. With anti riot design, suitable for use in flammable and explosive environments in chemical plants

debugging method
1. Range setting:
Press the "SET" button, the LED display and manual indicator light will turn red. Press the "" button to select the data bit to be modified (the selected data bit will flash). Press the "△" key to modify the data value of the selected bit (within the range of 0, 1, 2... 9). After completing the setting, press the "SET" button to confirm the modified parameter values, memorize and transfer to the measurement interval time setting. At this point, the indicator light is off.
2. Measurement interval time E setting:
After entering the interval time "E." setting, the monitor displays E. and the time value. Press the "" key to select the time data bit to be modified (the selected data bit flashes), and press the "△" key to modify the data value of the selected bit (within the range of 0, 1, 2... 9). Press the "SET" button to confirm the modified parameter value, memorize and transfer to the upper limit setting. If the upper and lower limit parameter values are not required to be set on site, the controller will return to the real-time level state and output a 4-20mA analog signal for setting the upper and lower limits on the secondary meter or computer in the control room.
3. Upper limit setting;
After entering the upper limit setting, the LED display flashes and the automatic indicator light displays in red. Press the "" key to select the data bit to be modified (the selected data bit flashes), press the "△" key to modify the data value of the selected bit (modification range 0, 1, 2... 9). Press the "SET" button to confirm the modified parameter values, memorize and switch to the lower limit setting. At this time, the display light is off.
4. Lower limit setting
After entering the lower limit setting, the LED display flashes and the overtravel indicator light displays in red. Press the "△" key to select the data bit to be modified (the selected data bit flashes), and then press the "△" key to modify the data value of the selected bit (within the range of 0, 1, 2... 9). Press the "SET" key to confirm the modified parameter value, remember and return the real-time level status.
5. Status setting:
In the state where the "work" indicator light is off, press the "manual/automatic" button continuously for 6 seconds, and the manual/automatic light will flip and switch to the corresponding state.
6. Working status:
Press the "Work" button, the work indicator light will turn on, and measurement will begin at the same time. After the measurement is completed, the display will show the height of the object level, and the probe will be suspended above to wait for the next measurement. The countdown of the measurement interval time ends in automatic mode, the work indicator light lights up to start automatic measurement, the measurement end display shows the height of the object level, and the probe is suspended above to wait for the next measurement.
7. Remote control status
In the state where the work indicator light is off, press the "remote control" button to turn on the work indicator light and remote indicator light, and start measuring at the same time. After the measurement is completed, the display will show the height of the object level, and the probe will be suspended above to wait for the next measurement. At this time, the work indicator light and remote indicator light are off.
