Multi-tube variable area flow meter block for oil, model VExA

Accuracy, precision and highly reliable operation of the VExa multi-tube variable area flow meters rely on our long-term experience and in-depth expertise in flow measurement equipment. With more than 75 years in flow meter design and manufacturing, Kytola knows how to address industrial oil flow lubrication needs with highest accuracy and precision.

The multi-tube variable area oil flow meter block VExA offers a solution to measure several streams of oil in individual channels. Kytola’s oil flow meter banks are highly adaptable measuring and monitoring devices. The VExA multi-channel oil flow meter is available with up to 7 flow tubes to accommodate most industrial application needs. VExA is especially suitable in circulating lubrication oil systems and other industrial applications where easy-to-read mechanical equipment are wanted. We believe in finding the most suitable solution for our customers’ needs. This is why our flow meters can also be tailor-made to customer specific requirements.

Kytola’s industrial variable area flow meters are made to last and to make flow measurement easy for the user. The design enhances high performance in demanding applications with low operational costs. Like all Kytola industrial flow meters, the oil lubrication flow meter block VExa with up to seven flow tubes is simple to install and it requires minimal maintenance. The VExA bank has an exceptionally visual and readable design even with very dark and black oils. Thanks to its versatility and several options to choose from, the VExA is one of most favored oil lubrication flow monitoring meter blocks in industrial applications.

Simplified the basic operational principle of a multi-tube VExA variable area flow meter block is the following: oil flow raises the float in the tapered tube of the flow meter. This increases the area for passage of the oil. The free area is related to the flow rate, oil viscosity and the weight of the float. In other words: the greater the flow, the higher the float is raised.

The VExA flow meter has a sturdy construction, it is made to withstand harsh industrial conditions. The flow tubes are made of heavy-duty impact resistant polymer. Each flow tube has its individual flow adjustment valve on the outlet. The block has a quick-change tube feature. End blocks are made of aluminium.
