摘要: A microbial membrane reactor for use in flow systems comprises a first element to receive the microorganisms and a second element to receive the flow channels. The two elements have planar interior surfaces which are pressed together separated by a membrane impervious to the microorganisms. The flow channels arranged in or on the surface of the second element serve to transport the liquid along the membrane so that the liquid can interact with the microorganisms arranged on the other side of the membrane. The geometry of the flow pathway and thus the geometry of the flow channels can be easily altered, in respect of the length, width and height of the channel, and adapted to practical requirements.

摘要: An electromagnetic flowmeter assembly is described in which an excitation field is set up across a flow conduit and electrodes are used to sense the electromagnetic field generated across the flow conduit as a result of interaction between the excitation field and fluid flowing along the flow conduit. The signals obtained from the electrodes are processed, together with stored calibration data, by processing circuitry to determine flow measurements and means is provided for dynamically updating the calibration data.

摘要: An electromagnetic flow meter is disclosed which can be used to measure flow in low conductivity fluids, for example alcohol, turpentine, oil or other organic solvents. In one embodiment, the electromagnetic flow meter includes an elongate flow conduit having a direction of elongation corresponding to a direction of fluid flow, magnetic field generating means for generating a magnetic field across the flow conduit and potential sensing electrodes for sensing a potential generated by the magnetic field in a fluid flowing through the conduit. Both the field generating means and the potential sensing electrodes of the flow meter are elongate in the direction of flow.

摘要: A conductivity sensor is described in which electrodes are held in a desired position within a housing of the sensor by a number of slots accurately positioned within the housing. In one embodiment the slots are integrally formed within the housing. Once the electrodes have been inserted into the slots a thermoset resin is poured into the housing and cured. A through bore is then drilled through the housing, the electrodes and the cured resin to form a flow conduit through the sensor. A dual frequency excitation technique is also described that allows a measurement to be obtained of a polarisation resistance of the electrodes. In one embodiment this measurement is stored and used to correct subsequent conductivity measurements.
