Calibration columns. What are they for? Jun 11 Do you need to know exactly the specific amount of chemicals that you must inject into a dosing process?
The calibration columns verify the volume provided by a dosing pump. Today we talk about this type of instrument. What are they used for? And how are they used? Figure 1. Sizes and connections The size of the calibration column will depend on the size of the pump that we are going to work with. Other options We have calibration columns with a protective frame, in bypass for large volumes, with dual scales in gallons and ml … and we study other specifications that may arise in an application for this type of equipment.
Calibration columns with stainless steel protection frame. Calibration columns in bypass. Some advantages of using calibration columns High reliability Reduced cost Direct reading Some disadvantages of using them in front of other systems Do not allow continuous measurements We are limited in the capacity of the instrument Pressure and temperature limitation These restrictions can be saved by using other volume measurement systems that we have in Tecfluid, such as the TM series turbine type flowmeters , one of the most used in the process industry, or the oscillating piston flowmeters COVOL series , a type of positive displacement flowmeter also called volumetric meter.

If possible you should run the calibration with the pump connected to the system that it feeds. The more closely you replicate the actual operating conditions of the pump, the more accurate your calibration will be. For non-corrosive or mild chemicals, PVC calibration columns are an economical choice. Designed from the ground up, our newest line of pump calibration columns feature a borosilicate glass interior for extreme chemical resistance and an even higher level of readability when compared to PVC columns.
The new design offers an integrated polycarbonate shield for full double-containment of corrosive chemicals with the added benefit of industry-leading impact resistance.
