How to measure a liquid sample with the portable density meter

To measure a liquid sample with a portable density meter, follow these general steps:

  1. Prepare the Meter: Turn on the portable density meter and ensure it is calibrated correctly according to the manufacturer’s instructions.
  2. Prepare the Sample: Ensure the liquid sample is at a stable temperature, as temperature can affect density measurements. If necessary, use a temperature-controlled environment or wait for the sample to reach equilibrium.
  3. Fill the Measurement Cell: Use a clean syringe or pipette to transfer a small amount of the liquid sample into the measurement cell of the portable density meter. Avoid introducing air bubbles.
  4. Measure the Density: Place the measurement cell into the portable density meter and start the measurement process according to the meter’s instructions. The portable density meter will measure the density of the liquid sample.
  5. Record the Results: Once the measurement is complete, the portable density meter will display the density of the liquid sample. Record this value for your records.
  6. Clean the Meter: After use, clean the measurement cell and any other parts of the portable density meter that came into contact with the sample according to the manufacturer’s instructions.
  7. Calibrate if Necessary: Regularly calibrate the portable density meter according to the manufacturer’s recommendations to ensure accurate measurements.

It’s important to note that specific instructions may vary depending on the model and manufacturer of the portable density meter, so always refer to the user manual for detailed instructions.

Servo tank gauges technology

Servo tank gauges are advanced level measurement devices used to accurately determine the level of liquid in storage tanks. They utilize servo technology, which involves the use of a servo motor and a sensing element to measure the liquid level. Here’s how servo tank gauges work:

  1. Principle: Servo tank gauges operate on the principle of hydrostatic pressure. The pressure exerted by the liquid in the tank is directly proportional to the height of the liquid column above the sensor.
  2. Components: A typical servo tank gauge system consists of a probe, a servo motor, a sensor, and a transmitter. The probe is immersed in the liquid, and the servo motor adjusts the position of the sensor based on the liquid level.
  3. Operation: The servo motor moves the sensor up or down to maintain a constant pressure difference between the reference pressure (at the bottom of the tank) and the liquid surface. The position of the sensor is then used to calculate the liquid level.
  4. Accuracy: Servo tank gauges are known for their high accuracy, typically within millimeter-level precision. This makes them suitable for applications where precise measurement is critical, such as in custody transfer operations.
  5. Applications: Servo tank gauges are commonly used in industries such as oil and gas, chemical, and water treatment, where accurate and reliable level measurement is essential for inventory management and process control.
  6. Advantages: Some of the key advantages of servo tank gauges include high accuracy, reliability, and suitability for a wide range of liquids, including corrosive and viscous fluids.

The servo tank gauges are an important technology for accurately monitoring liquid levels in storage tanks, ensuring efficient and safe operations in various industries.
