Hydraulic Flow Measurement

HydraulicCalculator 2New

Part No. HC2

Flow calculator for calculating discharge rates at backwater or sills.

Flow calculator for calculating discharge rates at backwater or sills with tangential flow or weirs as well as special structures.

HydraulicCalculator 2

Implemented calculation of discharge rates
Direct connection of 2- and 3-wire sensors possible
Ex Zone 1 (option)
Convenient menu-guided operatio

Problem solver for many hydraulic tasks

The HydraulicCalculator 2 has integrated calculation algorithms for calculating discharge rates at side weirs or weirs tending to backwater and compensates for the hydraulic calculation errors that occur when calculating discharge rate measurements according to Poleni. Supplementary calculation methods such as slot discharges with or without backwater, discharge under gates, storage level corrections at weir gates etc. complete the service profile. The metal-encapsulated and compact enclosure offers tool-free installation and assembly. Two analogue outputs and two relays are also integrated into the HydraulicCalculator 2.

Parameter settings are carried out conveniently using the rotary pushbutton in a menu-guided dialogue via a large, backlit colour graphic display.

An easy selection of the calculationrelevant parameters is just as much a matter of course as the implemented diagnostic tools for inputs and outputs, transmitter status, parameter changes, etc.. All required measurement and calculation values are displayed in clearly visible numerical values..

Typical Applications

Weir sills tending to backwater
Side weirs with tangential flow
Slot gates with and without backwater
Movable overflow weir flaps
Movable gates with underflow
Special applications with customised flow curve
and many more
