FIELD: technology for determining technical state of hydro-volumetric drives on basis of volumetric flow of working liquid.
SUBSTANCE: device has body with forcing hollow, wherein working liquid pressure meter is positioned, and with draining hollow. In the body, adjustable throttle is mounted in form of two circular washers, mated with each other by their end apertures. Each washer is made with through slit-shaped apertures. Device for adjusting throttle is made in form of handle, jointly connected to rotary washer, positioned on the side of forcing hollow of body and pressed to immoveable washer by means of spring. Indicator of working liquid flow is made in form of scale positioned on body and a pointer, mounted on the handle.
EFFECT: increased measuring precision due to excluding liquid leaks with simultaneously expanded spectrum of measurements; simplified construction.
