flow rate measurement Netherlands

...Venrius' portfolio includes a variety of variable area flowmeters. Metal tube variable area flowmeters, glass tube variable area flowmeters, and purge rotameters are the three main types. The volumetric flow rate of liquids and gases is measured using the float principle in metal and glass tube flowmeters. The purge flowmeter is intended for general use as a low-cost method of flow indication. It is suitable for the majority of non-critical purge applications that do not necessarily require high flow measurement accuracy.
