MEASURING WEIR

Flow rate measurement with measuring weir and FLOWBOX flow meter .......................

SUBJECT OF THE OFFER

The subject of our offer is a measuring weir intended for measuring momentary and total flow of the liquid in gravitational channels, 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 measuring weir or only flow meter FLOWBOX).

• .......................
• * Launching of our ultrasonic flow meter FLOWBOX in your facility (unlike many products of the competition) is very simple and in most cases, it doesn’t require a visit of specialized service – we provide factory pre-programmed (for the given type of flume or measuring weir) and pre-calibrated set (only one parameter needs to be adjusted).

ASSUMPTIONS

The liquid flow rate measurement with measuring weirs and water rise method 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 transducer.

The basic condition to apply the method is to provide free, undisturbed outflow of liquid. Moreover The measuring weirs can be used for treated wastewater without solid impurities.

MEASURING WEIR

We offer a wide range of measuring weirs to optimize the flow measurement (triangle measuring weirs, rectangular measuring weirs, trapezoid measuring weirs, circural measuring weirs). The measuring weirs made in accordance with ISO 1438:2008 "Hydrometry - Open channel flow measurement using thin-plate weirs", are installed in measuring wells or in existing ducts. The measuring weirs can be used for treated wastewater without solid impurities.
