Abstract:
The device serves to measure the flow since furrows of trapezoidal
section, with the following characteristic elements: the little down base =11 -
20 cm the big above base of 50 - 60 cm depth in consideration with the
stuffing of 18 - 30 cm and the inclination of the slopes m =1.5 The flowmeter
is composed of two metal sections with variable cross section, the first from
the trapezoidal form until a triangle form with down top and the second from
a triangle section to a trapezoidal form. The first section is provided with a
metal shutter for the emending in the slopes of the furrow. To stabilize the
flow regime, up the downstream of flowmeter, the furrow is shark with a
waterproof film. The technique solution is the subject of the patent
application for invention a/2006/00101. The construction of the product is
simple, reliable without mobile parts. The maximum possible measured flow
is up to 5 dm3
/s.
