The subject of our offer is an ultrasonic flow meter FLOWBOX intended for measuring momentary and total flow of the liquid in gravitational channels, with the use of measuring flume or measuring weir, basing on ISO standard or UNIKLAR-77 cataloque. 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.

FLOWBOX flow meter in basic performance consists of:
Measurement of the liquid flow is carried out based on the rising element:
Described measurement of the liquid flow, based on ISO standard or UNIKLAR-77 cataloque, with an ultrasonic flow meter FLOWBOX, is currently one of the most popular and proven methods for measuring liquid flow in the gravitational channels, which has been used on the market for many years now. Every year, several hundred of new locations are equipped with the flow meters FLOWBOX manufactured by us, which in great majority successfully fulfil assumed measuring functions. The basis of operation of the flow meter FLOWBOX is the measurement of ultrasonic beam passage time between the ultrasonic sensor and the surface of dammed up liquid by one of the standardized damming elements (measuring flume or measuring weir), on the basis of which the level of liquid’s damming up is determined, and then – after using appropriate conversion formula – current flow rate of the liquid is determined.
The basic condition for the use of this method is to provide laminar flow of the liquid through damming element (e.g. measuring flume) and to ensure free unhindered outflow.
The ultrasonic method used for measurement has many advantages – among others, it enables the lack of direct contact of the measuring sensor with contaminated or aggressive medium.
Depending on a local needs or requirements the basic performance of FLOWBOX flow meter can be enriched with many optional addittions. Inter alia we recommend:
