Stable flow measurement with electromagnetic DC technology
KROHNE has a long history of providing electromagnetic flowmeters to directly measure the total flow volume in dredging applications. And we have amassed a lot of experience. The KROHNE OPTIFLUX 4000 is now the preferred flowmeter for leading companies within the dredging industry. With a full-bore flow tube and several abrasion resistant obstruction less liners, these units are robust and easy to install. OPTIFLUX 4000 is specially calibrated for dredging applications and flow velocities and carries most relevant marine type approvals. Now we are presenting the next generation of instrumentation for dredging applications. The OPTIFLUX 4300 ERT can offer: volumetric flow, mass flow, velocity, density, solids concentration. The OPTIFLUX 4300 ERT combines the well-established KROHNE flowmeter technology with a high end non-nuclear density meter based on tomographic technology. This unique device can help to optimize dredging operations. Dredgers are essential and effective tools at keeping waterways and ports navigable and can also be instrumental in assisting with coastal protection, land reclamation and coastal redevelopment. The most efficient dredging techniques use large pumps and suction pipes to pick up and move the slurry mixture from the seabed. The largest dredgers have suction pips with diameters as large as 1300 millimetres. In most cases operators need to document how much material has been moved, measured by weight of solids. This is calculated by measuring both, the liquid flow rate and fluid density. Typically, a nuclear density meter is used to measure the solids content of the liquid and a flowmeter or flow velocity sensor is used to monitor the flow volume. The unique features of the OPTIFLUX 4300 ERT are: It is a combination of an electromagnetic flowmeter and a non-nuclear tomographic density meter in one instrument It offers a display showing solids distribution in real time, it is equipped with robust full-bore design for demanding applications, it has a abrasion resistant ceramic tiled liner and hard steel inlet rings, it offers velocity, density, mass flow, volumetric flow, solids concentration.
