How to choose the right calibration column for metering pumps?
It is important to choose the right calibration column for metering pumps. The flow rate and fluid delivery capabilities of the pump can be easily checked using calibration columns, also known as calibration cylinders or calibration tubes. The following steps will assist you in selecting the appropriate calibration column:
- Determine your prerequisites: Understand the flow rate range in which your metering pump will operate. This is important for choosing a calibration column with the right capacity.
- Consider the fluid's characteristics: Keep an eye on the characteristics of the specific fluid being pumped. These include viscosity, temperature, and chemical compatibility which may have an impact on the choice of calibration column materials. Some fluids may require specialized materials, such as stainless steel or glass, in order to prevent corrosion.
- Choose the column material carefully: While selecting pump calibration columns, it is vital that you select the material that is safe and easy to use. Ensure the material is corrosion-resistant and can easily withstand environmental challenges. You should also make selection wisely so that it complies with all applicable regulations.
- Focus on the capacity of the column: Another factor to keep in mind is the capacity of the column. It should be considered to support the highest and lowest flow rates, without overfilling or overflowing.
- Check the precision and resolution: It is mandatory to check the degree of precision and resolution that your application may require. If the metering pumps are used in water treatment applications across food industries, then calibration columns of high resolution may be needed. If you are using it for regular water treatment in other industries, more accuracy may be needed. Remember, the high precision would mean higher prices.
- Check the Mounting Options: Check the choices for mounting and connecting the calibration column to your metering pump system. Make sure it has the right connections and fittings for your setup.
- Consider the Maintenance and Cleaning Requirements: Consider the calibration column's ease of upkeep when considering maintenance and cleaning. For accuracy to remain, frequent cleaning is necessary.
Six Must-Follow Tips for Maintaining Pump Calibration Columns
Maintaining and calibrating calibration columns is critical for accurate analytical measurements. Here are essential tips:
1. Regular Inspection of your calibration column is important if you expect a lasting performance. Check columns for damages like blockages, cracks, and visible wear and tear on a regular basis and take necessary steps for rectification.
2. As calibration columns are filled with neutral fluids, there are all chances of debris getting settled on its corners. These sediments and debris may affect the measurement. Hence, they clean the columns regularly using a manufacturer-recommended chemical solution.
3. Establish a regular calibration schedule based on usage and manufacturer guidelines. Use approved reference standards during calibration. Performing calibration at regular intervals would help maintain its accuracy.
4. Maintain records of inspection and calibration procedures, as this would help your team track the column's performance over time and focus on concerns that need addressing.
5. Keep columns away from volatile substances, high humidity, and severe temperatures that could impair their effectiveness.
6. Carefully observe any alignment and positioning-related issues in pump calibration columns and fix them before they aggravate. This is because loosened columns would produce inaccurate measurements.
Beneficial Features of Calibration Columns Offered by Cannon Water Technology
Calibration columns can be used in several process industries. Their rugged construction and durability make them ideal for use in harsh environments. Here is a list of some beneficial features of calibration columns we offer. So, let’s have a look at them.
- These calibration columns are designed for determining pump flowrate using an industry-standard graduations scale. These columns feature a top-aligned, highly-visible graduated scale, allowing the operator to provide precise measurements in your preferred units. This also helps in enhancing readability.
- The graduation scale has a clear mylar overlay to add protection against harsh environments.
- Almost all calibration columns offered by Cannon Water are available in borosilicate glass or polyvinyl chloride, or PVC constructions. PVC calibration columns are ideal for mild or non-corrosive chemicals, while glass columns are economical for measuring corrosive chemicals. Compared to PVC construction, borosilicate glass offers a higher level of readability and helps improve overall productivity.
- Additionally, end caps are constructed using different materials such as CPVC, PTFE, and 316L stainless steel to ensure compatibility with several chemicals or fluids.
- Fabricated using high-quality materials, these columns can withstand stress, chemical resistance, corrosion, temperature variance, and other severe environmental conditions.
Applications of Calibration Columns
Owing to their undeniable features, calibration columns are used for various purposes, such as to
- Accurately insert appropriate dosage of chemicals in batch processes

2. Are calibration columns compatible with all types of metering pumps?
Yes, calibration columns are compatible with all types of metering pumps, including piston, peristaltic, and diaphragm pumps. These columns must be customized to meet the requirements of these pumps.
3. Can I utilize numerous calibration columns in parallel or series for complicated metering applications?
You can utilize multiple calibration columns in series or parallel to suit complicated metering requirements or test numerous parameters at once.
4. How should I size a calibration column?
Sizing a calibration column would involve several considerations. The following tips would help you achieve it effectively.
- Determine the maximum and minimum flow rates your metering pumps would handle.
- Decide upon the level of accuracy needed in your measurements.
- Choose the right material for the calibration column.
- Determine the diameter of the column and ensure it is large enough to provide you with a clear view of the liquid in a container. This diameter must also comply with your desired flow rate without causing excessive pressure drop.
- Next, focus on the height of the column, which should be sufficient enough to allow the expected range of fluid. This height can be calculated considering the pump’s flow rate and stroke length.
- See if the calibration column has graduated scales that would allow you to read the flow rate and volume carefully.
