WATER COUNTER COUNT UNIT Russian patent published in 2014 - IPC G01F15/06 

FIELD: instrumentation.

SUBSTANCE: count unit comprises case with mechanical digital counter fitted therein, magnetic coupling arranged therein to revolve in interaction with mating magnetic coupling of counter case articulated with impeller arranged in case flow section to revolve of water flow. Count unit comprises also the reduction gear to engage count unit magnetic coupling with mechanical digital counter drive wheel, permanent magnet eccentrically fitted on drive wheel of said counter, normally open magnetically operated sealed switch 10 arranged in said case to interact with permanent magnetic in rotation of said drive wheel to cause close/open cycle. Said count unit comprises load and break resistor 11, close load resistor 12 and four outputs 13-16 of water counter electric circuit. Note here that first output 13 is connected with one contact 17 of switch 10, second output is connected with one of contacts 18, third output 15 is connected with second contact 19 and contact 20 of resistor 12, fourth output 16 is connected with second contact 21 of switch 10 and second contact 22 of resistor 12.

EFFECT: expanded operating performances.
