Abstract
A non-invasive sensor for monitoring fluid material flowing in pipelines used in industrial and domestic processes, comprises a nonÂmetallic pipe SK1 forming a receptacle through which a process fluid can flow, and a sensor winding SK3 creating a magnetic field in the pipe. A pulsating magnetic field scans each sample of fluid with a sawtooth waveform sweeping each fluid sample to create a spectrum of its contents. Electronic circuitry and winding SK3 is contained in a Faraday cage SK4 to prevent interference and produces output signals that display the molecular content of the fluid flowing in the pipe sensor. Degaussing windings SK2 are included on the pipe. The sensor is useful for monitoring material type, moisture content, fluid contamination, water in oil for example, to indicate pollution levels and volume of any bacteria present in the process fluid.
Description
A FLUID SENSOR.
A Non-invasive Sensing Transducer for continuous monitoring of materials flowing in pipelines.
The present invention relates to a Sensing Transducer that can be used on pipelines carrying liquids, gases, and slurries, and non-invasively, monitor the the material.
Monitoring gases to determine the moisture content, or to determine that the correct material is flowing in the pipeline.
Monitoring fluids for the detection of contamination, or, for example, the measurement of water in oil, or, oil in water. The corruption of process recipes due to mechanical, or instrument failure.
The Sensing Transducer is a parametric device, and can be used to monitor variations from an approved standard.
The device can also be calibrated to detect, and monitor the volume of pathogenic material entrained in water, and milk intended for human consumption.
A compact device requiring only the expertise of a plumber to install it for instant service.
According to the invention, the sensor generates a continuous stream of spectra at a nominal frequency of 100 to 150 Kilo Hertz. The operating frequency is dependent on the resonant frequency of the complete installation of the sensor and, therefore, changes with its environment.
The Sensor assembly consists of a plastic tube (ski) the diameter of which is selected so that the sensor can be inserted seamlessly into the pipework of the process with which it is to be used.
The Sensor tube is fitted with degaussing windings at each end so that the contents can flow in either direction for measurement purposes (sk2).
The main Sensor transducer is located centrally with respect to the degassing's (sk3) and consists of a 10mm wide copper coating around the circumference of the pipe. A dual monostable vibrator provides the frequency which is injected into the pipe section via the copper section, while a magnetic field is generated at the same frequency through which the flowing material passes.
The monostable vibrator is triggered at the resonant frequency of the installation by a standard time integrated circuit.
The magnetic field generated at a chosen duty cycle allowing a time interval between each pulse to allow the sensor enough time to lose any residual charge Each pulse consisting of a frequency from 0 to the resonant frequency of the assembly, and the resulting scan, creates a compressed spectrum of the chemistry construction of the material flowing in the pipeline.
The output signal from the monostable is a pulse, the width of which varies with the amount of information of the chemistry of the flowing material.
This can be used in a number of ways, depending on what the user wants to know about the flowing material.
Example. Ultra Pure Water. Monitoring for contamination. The spectrum of an approved sample of the fluid is placed in memory. This is used to compare with the signal derived from the Sensor monitoring the fluid flow Example. Bacteria detection. Standard tap water is checked for pathogenic content and placed in memory The flowing tap water is compared with the memory sample. The volume of bacteria will be indicated continuously. Note, the sensor is non selective so it is not possible to identify the nature of the bacteria.
The whole Sensor Assembly consists of; a plastic pipe with wind ings, the centre sensor section with the electronic circuit is encased in a Faraday cage of aluminium, used to limit local interference, and enhance the operation of the system. The complete electronic circuit is shown (sk5),
