Description

I
Temperature Monitoring Device and Method The present invention relates, in general, to a temperature monitoring device and method for automatically measuring and communicating the temperature of a fluid to a receiver unit.
Temperature monitoring devices are well known and are used in a variety of applications where it is important to receive temperature data measurements.
Such applications may include legionella monitoring, food safety, paint storage, chemical manufacture and storage, pharmaceutical manufacture and storage, road and rail transport and the storage of artefacts.

*. In patent publication GB 2434207 a domestic plumbing system is disclosed in S...
which a water and energy cost monitor comprises temperature sensors and flow rate monitors disposed between a shower head and water source. When the shower head is in use and water is permitted to flow, data is provided to a 2. remote unit about the water temperature and flow rate. This way, a user can determine energy and water consumption and subsequently adjust temperature and flow rate so that the system is operating at maximum efficiency.
According to GB 2434207 unless a user is present to operate the shower head no flow of water occurs and if used the temperature sensor monitors the temperature of stagnant water.
According to a first aspect of the present invention, there is provided a temperature monitoring device comprising: a first inlet for receiving a fluid and an outlet for discharging the fluid from the device; a temperature sensor arranged to measure the temperature of the fluid in a flow path between the first inlet and outlet and generate temperature data; a communication unit connected to the temperature sensor for communicating the generated temperature data to a receiver unit; wherein the temperature monitoring device further comprises a first flow control valve operable between open and closed states to periodically permit the flow of the fluid between the first inlet and outlet and the temperature sensor, the communication unit and the first flow control valve are controllable by a microprocessor.

* 2 For example, strict guidelines and controls exist for the monitoring of systems where legionella can exist. Legionella is a gram negative bacterium including species that cause legionellosis or Legionnaires disease. Common sources of Legionella include cooling towers used in industrial cooling water systems, air conditioning systems and domestic hot water systems. Temperature is known to affect the survival of Legionellae and so regulations specify that potential sources of Legionellae are maintained at either a temperature above that which Legionellae can exist or below a temperature at which they become dormant.
Typically, in order to monitor the temperature of water, a trained operative must visit a site to operate the various taps to provide a water flow and temperature representative of normal usage. Such an approach can be subject to human error and costly to implement. Since the present invention permits an automated device and method of monitoring the temperature of a fluid, the present invention obviates or at least mitigates the sources of human error and excess costs.
Preferably, the temperature sensor is connected between the first flow control valve and the outlet. Preferably, a second inlet is connected to a second flow control valve operable between open and closed states to periodically permit the flow of the fluid between the second inlet and outlet, wherein the temperature sensor is connected between the second control valve and the S...

Preferably, when in use, the second inlet receives a fluid at a different temperature to the first inlet.
2:' The device can therefore comprise either one inlet connectable to, for example, a single water supply pipe which can be water supplied at a specified usable temperature or two inlets connectable to, for example, a hot and cold water supply pipe respectively.
Preferably, the microprocessor is programmed with data operable to control the temperature sensor to generate temperature data for a predetermined portion of time that the flow control valve is in an open state.
The predetermined portion of time can be sufficient to expel the stagnant fluid from the system so that the fluid reaches a temperature and flow rate indicative of real user requirements.
Preferably, the microprocessor is programmed with data operable to control the first and/or second flow control valve to periodically permit the flow of the fluid between the first and/or second inlet and outlet for a predetermined period of time.
The first and/or second control valves can be operable to conform to guidelines specified to cover the frequency of temperature testing and the flow rate of fluid required in testing.
If required the predetermined period of time can be made dependent upon the temperature of the fluid. * S S...
Preferably, the microprocessor is located within the device and is S...
: programmable remotely. Preferably, the device comprises an internal power source which can be a battery unit.
Preferably, the communication unit is configured to communicate the temperature data to the receiver unit as a wireless communication.
Alternatively, the communication unit can be hard wired to the receiver unit.
Where wireless communication is employed, the wireless communication is selected from SMS, GSM, GPRS, SRD (Short Range Devices), Low Power Radio, Infra-Red or Bluetooth communication.
Preferably, the communication unit communicates an alarm signal if the temperature data corresponds to a predetermined value or range. The alarm can automatically trigger a safety protocol system to be followed.
Preferably, the fluid is a liquid or a gas. Where the fluid is a liquid, the fluid is preferably water.
The present invention can be applied to, for example, domestic or industrial heating and water systems. According to a second aspect of the present invention, there is therefore provided a plumbing assembly including a temperature monitoring device as discussed herein, wherein the first inlet is connected to a fluid source, the outlet is connected to a waste outlet and the first flow control valve is operable to permit the flow of the fluid out of the waste outlet.
By connecting the outlet direct to a waste outlet, the outlet path by-passes a tap .... outlet visible to a user and so temperature monitoring can be carried out hidden r. from users. e. *
According to a third aspect of the present invention, there is provided a plumbing assembly including a temperature monitoring device as discussed
S
herein, wherein the first inlet is connected to a fluid source, the outlet is connected to a tap outlet and the first flow control valve is operable to permit the flow of the fluid out of the tap outlet.
By connecting the outlet to a tap outlet, the device can be plumbed in series with the tap outlet.
According to a fourth aspect of the present invention, there is provided a method of automating the monitoring of the temperature of a fluid comprising: periodically opening a first flow control valve to permit the fluid to flow along a flow path between a first inlet and outlet; measuring the temperature of the fluid along the flow path; generating temperature data of the fluid; and transmitting the generated temperature to receiver unit, wherein at least one of the generating temperature data, transmitting temperature data and periodically opening the first flow control valve are controlled by a microprocessor.
Preferably, the method includes generating temperature data for a predetermined portion of time that the flow control valve is in an open state.
More preferably, the method includes controlling the first flow control valve to periodically permit the flow of the fluid between the first and/or second inlet and is outlet for a predetermined period of time.
*::::* It is therefore provided a temperature measuring device and method capable of :::: providing a close representation of temperature behaviour over a specified operating time. Improved data collection and accuracy is thereby obtained.
r*':* Such improved data collection can be used as an indication of early legionella activity in a water system and allow action to be taken to avoid contamination of the system before it is too late to do so. The device and method also provide real-time transmission of temperature data.
