Currently, the problem of accurate metering micro-flows (up to 100 ml / min) liquid components of technological processes is acute in the chemical and nuclear industries. This problem is due to the fact that peristaltic pumps are used for batching, in which the slope of the flowrate characteristic changes with time. This is due to the wear of the flexible hose due to numerous compression cycles. Using of peristaltic pumps is due to the fact that in most technological processes in the nuclear and chemical industries, aggressive reagents are used and the use of other types of pumps is problematic because of the need to contact the moving parts of pumps directly with the environment. This work describes the developed flowrate sensor, which is a capillary flowmeter, a measured volumetric flowrate. Metrological and production tests of the developed flowmeter are conducted and described. The variants of realization of the device of the automatic dispensing of low flowrate of aggressive and radioactive liquids.
