Abstract

Modular measurement system for one or more parameters, with exchangeable sensorcartridges. The measurement system can be used for compressed air, gases and liquids. Servicing is a matter of exchanging the sensorcartridge. The system contains a safety mechanism, which prevents accidental exchange of a sensorcartridge while the system is pressurized.

Description

Modular measurement system with exchangeable sensorcartridges Introduction
Servicing and recalibration of field measurement equipment devices, for example insertion flow meters is in general a cumbersome job. The entire device needs to be uninstalled and sent back to the manufacturer for recalibration.
In this invention, we describe a modular measurement system, in which one or more sensors are packaged in a cartridge-shaped probe, hereinafter referred to as "sensorcartride". The sensorcartridge can be easily and safely exchanged by a new one, so calibration is not an issue anymore.
An aspect of the invention provides a safety mechanism, consisting of an adjustable safety line.
According to an embodiment the sensorcartridge communicates with a data display unit, using a digital serial protocol.
According to an embodiment the probe cartridge can be rotated to facilitate readout of the data display unit.
According to an embodiment the sensorcartridge may include a silicon mass flow sensor.
According to an embodiment, the sensorcartridge contains multiple sensors for measuring fluid consumption, pressure, temperature and humidity Also, for example, the sensorcartridge may contain a gas flow or liquid flow sensor.
According to an embodiment, the sensorcartridge contains sensor elements in which one or more parameters for flow, pressure, temperature and humidity are combined.
The sensorcartridge includes a sensing structure, e.g. a flow sensor element, capable of, or configured for measuring changes in a defined physical parameter. The sensorcartridge is configured to process these physical parameters into electrical digital signals.
The modular measurement system is not limited to the internal sensor technologies, nor to the parameters to be sensed. It can be applied on all possible applications.
The modular measurement system is also not limited to the physical shape of the probe cartridges. As preferred embodiment, we describe a system where the sensorcartridge is mounted using a fixation ring.
The invention will now be described, referring to the drawings which show a non-limiting embodiment of the invention.
Figure 1 depicts a 3D exploded side view of the entire system with the sensorcartridge and the digital data display unit.
Figure 2 depicts a 3D view of the sensorcartridge and the digital data display unit.
An exploded view of a non-limiting example of the invention is described in Figure. 1 and 2. The data processing unit (1), in this example manufactured out of aluminum and plastic, has a sensorcartridge reception hole, where the sensorcartridge (2) is mounted, using a fixation ring (3) which accommodates a safety mechanism. In this example, the safety ring has internal thread, but it may also be implemented with a bayonet fitting or a combination between thread, push/pull and bayonet fitting mechanisms. The housing accommodates an electronics board. This board provides the required field output signals and digitally communicates with the sensorcartridge. The sensorcartridge is equipped with circular contacts. The electrical connection between the sensorcartridge and the data processing unit is established using gold-plated spring loaded ball contacts and circular electric conduits (9). These ball contacts can be on either side, this means they can be on the main board or on the sensorcartridge. The sensorcartridge(2) in this example is made of aluminum and injection molded plastic. Various sensors are mounted inside the sensorcartridge(2). The probe (7) and sensors(8)of the sensorcartridge are sealed with potting with polyurethane or epoxy.
To prevent the sensorcartridge from shooting out of a pressurized environment, one or two safety lines(4) can be mounted onto the sensorcartridge. The fixation ring (3) prevents accidental removal of the safety lines. The safety lines are retained using an auto brake system (5) and an end stop (6)
Applications of the invention are gas and liquid flow, pressure, temperature, oil content and dew point measurement of any medium.
The skilled person will appreciate that the invention is not limited to the described embodiments nor the parameters to be measured.
The skilled person will appreciate that the probe cartridges can have various shapes, colors and dimensions. Particularly, a sensorcartridge may have a unique shape to prevent mis-mounting thereof.
