VENTURI MEASURING FLUME

Flow rate measurement with FLOWBOX flow meter and venturi KPV flume
.......................

FLOWBOX flowmeter with KPV Venturi flume

SUBJECT OF THE OFFER

The subject of our offer is a Venturi flume intended for measuring momentary and total liquid's gravitational flow with the use of an ultrasonic flow meter FLOWBOX. Upon request, it’s also possible to carry out pre-investment technical consulting, as well as subsequent installation, launching* and protocol-based delivery of flow meter for the use. We also sell individual elements of the measuring set manufactured by us (e.g. only Venturi flume or only flow meter FLOWBOX).

ASSUMPTIONS

The liquid flow rate measurement with Venturi flume and water rise method in rectangular channels is based on the actual liquid level measured by the ultrasonic sensor (radar sensor, optional) at the hydraulic structure converted into the value of flow ratio by the measuring transmitter.

The basic condition to apply the method is to provide, undisturbed and laminar flow in a measuring flume and free outflow of liquid from the measuring flume.

VENTURI FLUME

Venturi flumes in accordance with UNIKLAR-77 data sheet are intended for measurement of volumetric flow rate in rectangular channels with gravity flow. The flumes are made of stainless steel and enable measurements within the range specified in the table below. The self-cleaning feature of the flumes enables measurements of media with solid impurities. CAUTION! We also provide Khafagi-Venturi QV302...QV316 flumes.

The flume is embedded in concrete in a rectangular channel with minimum gradient maintained and subcritical flow. The measurement in lower range for a specific flume type will be encumbered with a significant error.
