High-accuracy flowmeter

The latest release of the Promass F Coriolis mass flowmeter offers accuracy and reliability, making it suitable for use in most process industries.

Endress+Hauser wet calibrates every Promass F flowmeter on a high-accuracy flow rig. In wet calibration, a predetermined volume of water is allowed to flow through the flowmeter, and the mass of water, and therefore volume, is measured in a highly accurate, accredited weigh scale at the other end. The volume of liquid that has flowed through and been measured by the test meter is compared to the initial reference volume and the errors calculated. Wet calibration thus delivers accuracy when the flowmeter is put in actual use.

The flowmeter's specification of 0.05% o.r. (of reading) is based on an accredited calibration flowrig with an accuracy of 0.015%, ensuring that the accuracy stated is the accuracy achieved.

Coriolis flowmeters are often used for dosing - for example, chlorine in water treatment plants, flocculants in mining, or additives in the food industry. This dosing must be highly accurate or else the end product will suffer in quality, and expensive additives may be wasted.

The high-accuracy Promass F can help to prevent wastage and reduce costs.
