1、 Installation precautions

1. Installation location selection
   • Avoid interferenceThe installation position should be far away from areas that may generate turbulence or vibration such as water inlet, water outlet, mixer, etc., to ensure that the floating ball can rise and fall smoothly with the liquid level.
   • vertical installationThe float level controller needs to be installed vertically, with a tilt angle not exceeding 5 °, otherwise it may affect the movement and measurement accuracy of the float.
   • Avoid blind spotsEnsure that the installation location covers the entire liquid level measurement range and avoids measurement blind spots caused by pipeline or equipment obstruction.
2. Fixed and sealed
   • Firmly fixedUse appropriate brackets or fixtures to securely fix the controller to prevent loosening or displacement due to vibration or liquid level fluctuations.
   • Sealing treatmentFor outdoor or humid environments, it is necessary to seal the electrical connection parts to prevent moisture from entering and causing short circuits or damage.
3. electrical connection
   • Correct wiringStrictly follow the instructions to connect the power line, signal line, and grounding wire, ensuring that the wiring is firm and not loose.
   • Voltage matchingThe power supply voltage should be consistent with the rated voltage of the controller to avoid equipment damage caused by high or low voltage.
   • Explosion-proof requirementsWhen used in flammable and explosive environments, it is necessary to choose controllers that meet explosion-proof standards and follow relevant installation specifications.

2、 Precautions for use

1. Media compatibility
   • Material SelectionSelect appropriate float and shell materials based on the properties of the measuring medium, such as corrosiveness, viscosity, temperature, etc. For example, for corrosive media, stainless steel or plastic floating balls and controllers should be selected.
   • Avoid blockageFor media containing solid particles or impurities, a filter should be installed in front of the controller to prevent impurities from jamming the float or damaging the controller.
2. Liquid level range setting
   • Reasonable settingSet the liquid level control range according to actual needs to avoid frequent start stop or loss of control of the equipment caused by excessively high or low set values.
   • Calibration verificationAfter installation, liquid level calibration and functional verification are required to ensure that the controller can accurately reflect the actual liquid level and control related equipment normally.
3. operation monitoring
   • regular inspectionRegularly check whether the floating ball moves flexibly, whether the electrical connections are firm, whether the sealing is good, etc., and promptly discover and deal with potential problems.
   • exception handlingIf the float is found to be stuck, the liquid level display is abnormal, or the control fails, the machine should be stopped immediately for inspection, and the fault should be eliminated before resuming operation.

3、 Maintenance and upkeep

1. Cleaning and maintenance
   • regular cleanupRegularly clean the surface of the float and controller of dirt, impurities, etc., keep the equipment clean, and prevent affecting measurement accuracy.
   • Lubrication treatmentFor components that require lubrication (such as floating ball shafts), it is necessary to regularly add an appropriate amount of lubricant to ensure smooth movement.
2. Component replacement
   • Timely replacementFor severely worn or damaged components (such as floating balls, seals, etc.), they should be replaced in a timely manner to avoid affecting equipment performance and safety.
   • Genuine partsWhen replacing components, original parts or substitute products that meet specifications should be selected to ensure equipment compatibility and reliability.
3. Storage and transportation
   • Moisture-proof and dust-proofDuring storage and transportation, the controller should be placed in a dry, ventilated, and non corrosive gas environment to prevent moisture, dust, or damage.
   • avoid collisionDuring transportation, handle with care to avoid severe collisions or falls that may damage the equipment.

4、 Safety precautions

1. Electrical safety
   • Power off operationWhen making electrical connections, repairing or replacing components, it is necessary to first cut off the power supply to ensure safe operation.
   • grounding protectionEnsure good grounding of the controller to prevent electric shock accidents caused by leakage.
2. Operating Specifications
   • Comply with regulationsOperators need to be familiar with the working principle and operating procedures of the controller, and strictly follow the instructions for operation and maintenance.
   • training and educationProvide professional training and education to operators to enhance their safety awareness and operational skills.
3. emergency response
   • Develop contingency plansDevelop emergency response plans for possible malfunctions or abnormal situations to ensure prompt and effective handling.
   • Equipping equipmentEquip necessary emergency response equipment and tools on site, such as insulated gloves, screwdrivers, multimeters, etc.

5、 Special working condition precautions

1. high temperature environment
   • high-temperature resistant materialWhen used in high-temperature environments, it is necessary to select float balls and controllers made of high-temperature resistant materials, and ensure that the seals can withstand high temperatures.
   • Heat dissipation measuresFor controllers with high heat generation, heat dissipation measures should be taken, such as adding heat sinks, fans, etc., to prevent equipment from overheating and damage.
2. low-temperature environment
   • Antifreeze treatmentWhen used in low-temperature environments, the controller needs to be treated with antifreeze, such as adding antifreeze, insulation materials, etc., to prevent equipment from freezing, cracking, or damage.
   • Preheating startBefore starting the equipment in a low-temperature environment, preheating treatment can be carried out to ensure that the equipment can start and operate normally.
3. Corrosive environment
   • corrosion preventionWhen used in corrosive environments, the controller needs to be treated with anti-corrosion measures, such as selecting corrosion-resistant materials and applying anti-corrosion coatings.
   • regular inspectionRegularly inspect the corrosion of the controller, promptly identify and address corrosion issues, and prevent equipment damage or leakage.
