Features
Using capacitive force sensor is the new product key core to realize high precision, high stability, completely changed the original strain type target flowmeter temperature drift is big, poor ability to resist overload (shock), such as static sealing point restrictions, not only played a target flowmeter the original technical advantages, at the same time have comparable to volumetric flowmeter measurement accuracy, together with its unique anti-jamming performance, resistance to impurities, in addition to substitute for conventional flow measurement can measure flow problems, especially in small flow, high viscosity, easy clot blocking, high and low temperature, strong corrosion, strong vibration, flow measurement has the very good adaptability in difficult conditions.At present, it has been widely used in various fields such as metallurgy, petroleum, chemical industry, energy, food and environmental protection.

Note：Actual pressure drop=（Actual flow / full scale flow）²×Full range maximum pressure drop.
2、Type selection calculation
The selection of all NBL series target flowmeters shall be calculated to convert the actual flow rate into the equivalent standard flow rate, and then select the appropriate caliber and model according to the table.
The formula is as follows：
