1. How to adjust the water tank level flowmeter? The adjustment method of the water tank level flowmeter varies depending on the type and steps, and the core is to calibrate the zero point and full range. 1. Installation inspection of ultrasonic liquid level flowmeter: Ensure that the sensor is installed vertically, avoiding obstacles and water flow impact points. Power on preheating: Connect the power supply and preheat for 15-30 minutes to put the instrument into a stable state. Parameter setting: • Range setting: Set the range based on the actual height of the water tank (e.g. 0-5 meters). • Zero point calibration: When the water tank is empty, perform zero point calibration in the menu to make the display and Qin family values 0. Full range calibration: After the water tank is filled, perform full range calibration to make the displayed value consistent with the actual liquid level. Signal output adjustment: Set the correspondence between 4-20mA output (such as 4mA corresponding to 0 liquid level, 20mA corresponding to full liquid level). Stability adjustment: Adjust through time constant or filtering function to avoid frequent fluctuations in display values
2. Installation inspection and zero position adjustment of magnetic flap level gauge: Ensure that the level gauge is installed vertically and the connecting pipe valve is open. When the water tank is empty, manually adjust the magnetic flap display to zero position. Upper and lower limit settings: If equipped with a switch output function, the alarm value can be set by adjusting the switch position (such as high or low alarm)
3. Installation and zero calibration of pressure level gauge: The sensor is installed at the bottom of the water ta

2. What are the types of automation instruments?
There are various types of automation instruments, mainly including the following:
1. Flow meters are used to measure the flow rate of fluids in pipelines and are widely used in the fields of chemical, petroleum, water treatment and other industries.
. The types of slip include electromagnetic flow meters, mass flow meters, ultrasonic flow meters, etc. Secondly, pressure gauges are used to measure pressure and play an important role in industrial automation control. By amplifying the pressure perceived internally, the pressure signal is converted into a readable indicator value or electrical signal output.Thirdly, a thermometer is used to measure temperature and is one of the commonly used instruments in automation control.
. It can measure and display the temperature of various media such as air, liquid, and solid surfaces. Common thermometers include resistance thermometers, thermocouple thermometers, etc. 4. Level gauges are mainly used to measure the liquid level height of liquids in containers. Monitoring the liquid level is crucial in various industrial production processes and helps to avoid safety hazards. Common level gauges include magnetic flap level gauges, ultrasonic level gauges, etc.
