1.1 Solution for partially filled pipes

The TIDALFLUX 4000

TIDALFLUX 4000 flow sensor with integrated and non-contact capacitive level measuring

TIDALFLUX 4000TIDALFLUX 4000 system provides accurate flow measurement in partially filled pipes. TIDALFLUX is designed to measure reliably between 10% and 100% of the pipe cross section. The integrated level sensors in the liner are in no contact with the liquid and are therefore insensitive against fat and oil floating on the surface.

PRODUCT FEATURES 1

Robust contruction

Robust contructionRobust contruction The TIDALFLUX 4000 has been designed for measuring all water and wastewater applications including groundwater, potable water, wastewater, sludges and sewage, industry water and salt water in partially filled pipes. The sensor is available for a wide diameter range of DN200 up to DN1600 for flow rates up to 90,000 m3/hr. The TIDALFLUX 4000 causes no pressure loss and allows for bi-directional flow metering. Filters or straighteners are not required. The flowmeter can be installed underground and allows for constant flooding (IP 68). A measurement chamber is not necessary, saving substantial costs. The TIDALFLUX provides years or reliable measurements as it has no internal moving parts and nothing can wear. The flowmeter has a field proven and unsurpassed lifetime. In addition, the TIDALFLUX 4000 in combination with the IFC 300 converter offers extensive diagnostic capabilities such as continuous monitoring of the converter, the sensor electrodes and electric functions.

Communication

CommunicationCommunication The TIDALFLUX 4000 can be provided with state-ofthe-art fieldbus communication systems. Data is

transmitted by HART ® or Modbus and then

forwarded to a management system.

1 PRODUCT FEATURES

1.3 Measuring principle

The TIDALFLUX 4000 is an electromagnetic flow sensor with an integrated capacitive level measurement system, designed for electrically conductive process liquids. The flow rate Q(t) through the tube is: Q(t) = v(t) x A(t)

Q(t) = v(t) x A(t), in which

Q(t) = v(t) x A(t)Q(t) = v(t) x A(t) v(t) = Flow velocity of liquid product A(t) = Wetted area of tube section.

The flow velocity is determined on basis of the known electromagnetic measurement principle. The two measuring electrodes are located in the lower part of the measuring tube, on a level of approx. 10% of the inner diameter of the pipe in order to get a reliable measurement to a level of 10%.

An electrically conductive fluid flows inside an electrically insulating pipe through a magnetic field. This magnetic field is generated by a current, flowing through a pair of field coils. Inside of the fluid, a voltage U is generated: U = v * k * B * D

U = v * k * B * D

U = v * k * B * DU = v * k * B * D

in which: v = mean flow velocity k = factor correcting for geometry B = magnetic field strength D = inner diameter of flow meter

TIDALFLUX 4300 F

The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v and thus the flow rate q. The signal voltage is quite small (typically 1 mV at v = 3 m/s / 10 ft/s and field coil power of 1 W). Finally, a signal converter is used to amplify the signal voltage, filter it (separate from noise) and convert it into signals for totalising, recording and output processing.

TIDALFLUX 4300 F

The wetted area A is computed from the known inside diameter of the pipe by the patented capacitive level measurement system that is built into the measuring tube liner. The required electronics unit is accomodated in a compact housing that is mounted on top of the measuring sensor. This electronics is connected to the remote IFC 300 F converter by means of a digital communication line.
