FLOW METER, PRIMARILY FOR USE WITH THE ENSURING THE UNIFORMITY OF MEASUREMENTS Russian patent published in 2018 - IPC G01F15/00 G01F15/06 

FIELD: measuring equipment.

SUBSTANCE: flowmeter (1) is described primarily for operation with uniformity of measurement, having housing (2), at least one data processing device (3) located in housing and interface (4) located in the housing for communicating with external control device (5) data processing device (3) being configured to record data via interface (4). Illegal effect on data processing device (3) is prevented, characterized in that in housing (2) there are at least two write-protection sensing elements (7a, 7b) wherein the outer side of the housing has socket (8) for at least one write-protect operation element (9), and this write-protect operation element (9) inserted in socket (8) moves the write protection sensing elements (7a, 7b) to write-protect status, that the write protection state of the write-protection sensing elements (7a, 7b) is detected by the data processing device (3) and when the write protection state of at least one of the write protection sensing elements (7a, 7b) is detected by data processing device (3), data recording via interface (4) to data processing device (3) is at least partially prevented.

EFFECT: technical result is the provision of an anti-impact mechanism for flow-through flowmeters that have built-in interface, by means of which the flow meter can be influenced by the flow data processing device and, by using which, a non-purely mechanical access control is implemented.
