FIELD: measurement technology.
SUBSTANCE: stand has water-proof chamber with water. Chamber is provided with partition disposed transverse to chamber. Partition is made for mounting of meter to be calibrated. Opposite edge walls of chamber are made in form of membranes; one membrane is connected with electromagnetic drive. Pressure transducers are disposed at both sides of partition; pressure transducers are connected to pressure difference transducers. Stand also has test signals generator, regulator and power amplifier.
EFFECT: imitation calibration of vortex water meters under conditions being close to real conditions of operation.
