1. Introduction

MetPak RG is a compact and lightweight multi-sensor instrument that measures the most essential weather parameters. Gill ultrasonic technology, as used in the proven WindSonic instrument, measures wind speed and direction. Temperature and Humidity are measured and Dewpoint calculated using an industry standard probe housed in a naturally aspirated radiation shield. Barometric pressure is measured using an industry standard sensor.

The customer is able to add one supplied digital contact closure rain gauge.

The MetPak RG combines all the instrument data into a single combined data string. This may be configured for digital ASCII RS232/RS422/RS485 (2 wire point to point) and digital SDI-12 outputs.

The instrument uses a rugged mounting clamp that attaches to any vertical pipe up to 58mm (2.3 inch) diameter.

An electrical Hub box is fitted to the mounting bracket for termination of the Rain Gauge Cable and Power/Data cable.

1.1 Principle of Operation

1.1.1 Wind Speed and Direction Sensor

The MetPak RG uses the WindSonic wind speed and direction sensor. The WindSonic measures the times taken for an ultrasonic pulse of sound to travel from the North transducer to the South transducer, and compares it with the time for a pulse to travel from S to N transducer. Likewise times are compared between West and East, and E and W transducer.

If, for example, a North wind is blowing, then the time taken for the pulse to travel from N to S will be faster than from S to N, whereas the W to E, and E to W times will be the same. The wind speed and direction can then be calculated from the differences in the times of flight on each axis. This calculation is independent of factors such as temperature.

Figure 2 Compass points

Figure 2 shows the compass point and polarity of U and V if the wind components along the U and V axis are blowing in the direction of the respective arrows.

1.1.2 Radiation Shield

The Multi-Plate Radiation Shield protects temperature and relative humidity sensors from error-producing solar radiation and rain. This shield relies on a combination of plate geometry, material and natural ventilation to provide effective shielding.

1.1.3 Temperature and Relative Humidity Sensor with Dewpoint Output

The Rotronic HygroClip module is a complete instrument, with integrated temperature compensation. Calibration data is maintained within the integrated electronics. It provides digital output signals for Relative Humidity, Temperature and Dewpoint to the MetPak RG Hub box.

Position of Temperature and Relative Humidity Probe in the Radiation Shield.

1.1.4 Barometric Pressure

Barometric pressure output is provided by a solid-state device fitted on to the circuit board in the MetPak RG Hub box. Vent to atmosphere is via a Gortex filter which also protects the pressure sensor from the effects of wind and rain.

1.1.5 Rain Sensor (DIG1 Input)

Rainfall is measured by the well-proven tipping bucket method. Rain is collected by a funnel and is passed to one of the two buckets situated at either end of a short balance arm. The balance arm tips when the first bucket is full, emptying this bucket and positioning the second bucket under the funnel. The tipping process repeats indefinitely as long as the rain continues to fall, with each tip corresponding to a fixed quantity of rainfall; at each tip the moving arm forces a magnet past a reed switch, causing contact to be made for a few milliseconds.

The Rain Gauge is connected to the MetPak RG Digital input, which detects when two dedicated terminals are short circuited (less than 1k ohm).

2. Installation

MetPak RG has been designed to meet and exceed the stringent standards listed in its specification (see Para 6.1).

2.1 Pre-Installation Checks

MetPak RG Wind Sensor and Hub Box.

As with any sophisticated electronics, good engineering practice should be followed to ensure correct operation:

 Ensure the MetPak RG Wind Sensor will not be affected by other equipment operating

locally, which may not conform to current standards, e.g. radio/radar transmitters, generators etc.

 Avoid mounting in the plane of any radar scanner – a vertical separation of at least 2m

should be achieved.

 When installing MetPak RG near radio transmitting antennas, ensure that the

mounting position fulfills the following minimum separations (all round):

 VHF IMM – 1m

 MF/HF – 5m

 Satcom – 5m (avoid likely lines of sight)

 Use cables recommended by Gill (see Para 2.2.3). If cables are cut and re-connected

incorrectly (perhaps in a junction box) then EMC performance may be compromised if cable screen integrity is not maintained.

 Avoid earth loops – wire the system in accordance with these installation guidelines.

 Ensure that the power supply operates to the MetPak RG specification (see Para 6.1)

at all times.

 Avoid turbulence caused by surrounding structures that will affect the accuracy of the

sensors such as trees, masts and buildings. The WMO make the following recommendations. The standard exposure of wind instruments over level open terrain is 10m above the ground. Open terrain is defined as an area where the distance between the sensor and any obstruction is at least 10 times the height of the obstruction.

 Keep away from building exhaust vents, machinery and motors.

Rain Gauge

The site chosen to install the rain gauge will depend in part on the application to which

it is being put and in part on the particular circumstances at the site. But if possible site the rain gauge so that the distance between the rain gauge and an obstruction, such as Trees or buildings is at least as great as twice the height of the obstruction. If the application is very specific, such as monitoring a building site, then the siting of the rain gauge is largely prescribed by use.

NOTE:

No two rain gauge designs are ever likely to produce identical results, and identical rain gauge can give slightly different catches even when sited close to each other.

Customers with 2 or more sets of equipment must not swap around rain gauges with MetPaks without using MetSet to change the calibration figure.

2.2 Installation

2.2.1 Bench System Test

Prior to physically mounting the MetPak RG in its final location, we strongly recommend that a bench system test is carried out to confirm the system is configured correctly, is fully functional and electrically compatible with the selected host system and cabling (preferably utilising the final cable length). The required data format, units, output rate, and other options should also all be set up at this stage.

Note that MetPak RG is supplied with a matching Rain Gauge and its tip calibration factors will have been pre-programmed into the MetPak hub box. If a replacement Rain gauge is used then the Hub box will need re-programming using Gill MetSet Software with the new tip calibration factor (if this has changed).

Cabling (unused wires)

Any unused wires in the connecting cables should be connected to ground preferably at the user equipment end.

Cabling protection

The Cable should be secured:

 With cable clamps or equivalent at regular intervals such that the hub

box cable gland does not support the cable weight.

 Away from the mounting bolts to prevent chaffing of the cable.

NOTE. Install appropriate strain relief support to the cable. If possible, pass the cable through the mounting pole.

Earthing

To ensure correct operation and for maximum protection from lightning, a separate lightning rod system is recommended to protect the system.

You can also earth the MetPak RG through its mountings or by connecting a grounding cable (minimum of 6mm² copper wire) to a spare MetPak RG metalwork bolt hole. Clean off any paint that might prevent a good connection.

When you connect the communications cable ensure that the screen has a connection to the hub box case.

Routing Cables through the Hub Box Glands

NOTE: The MetPak RG Hub Box cable glands contain spring loaded metal leaves that are designed to make a ground contact with cables that have an overall braid screen. Care is therefore required when inserting and removing cables through the glands to prevent damage to the metal leaves.

2.2.6 Mounting MetPak RG

MetPak RG uses a mounting clamp suitable for attaching to a vertical pipe with a diameter of 30-58mm (1.2 to 2.3 inches). When mounting MetPak RG, consider the position, orientation and alignment of the unit.

Note that the mounting pipe should first be degreased and when assembling the MetPak clamp assembly the outer clamp nuts need to be tightened evenly to a torque figure of 3 Nm.

The moving plate part of the clamp needs to be reversed for poles below 38 mm diameter.

Position

It is the responsibility of the customer to ensure that the MetPak RG is mounted in a position clear of any structure, including the mounting post, which may obstruct the airflow or induce turbulence.

CAUTION. Do NOT mount the MetPak RG in close proximity to high-powered radar or radio transmitters. A site survey may be required if there is any doubt about the strength of external electrical noise.

Orientation

Normally, the MetPak RG is mounted on a vertical pole, ensuring a horizontal Measuring Plane (see Figure 11).

For indoor use the unit may be mounted with the Measurement Plane set to any required orientation.

Alignment

The MetPak RG Wind Sensor should be aligned to point to North, or other required reference direction.

There are two arrows, a coloured rectangle, and an alignment notch on the WindSonic Wind Sensor that should point to North to aid alignment (See Figure

11).

Note. It is usually simpler to work first with a compass at ground level and identify a suitable landmark and its bearing.

Note. The North arrow alignment marker is now rotated by 180 degrees compared

Interference

Always check the installation to ensure the MetPak RG is not affected by other equipment operating locally, which may not conform to current standards, e.g. radio/radar transmitters, boat engines, generators etc.

See Para 2.1 for guideline details.

2.2.7 Mounting the Rain Gauge

The rain gauges tipping bucket mechanism is immobilised before shipping to prevent damage in transit. To release the mechanism, remove the funnel from its base by unscrewing the three nylon thumbscrews. Remove the piece of foam from under the bucket mechanism. This foam may be saved and used whenever the rain gauge is moved.

The MetPak RG mounting arrangement options: -

Baseplate Mounting

Due to the low weight of the rain gauge (1kg approximately) it must be mounted securely, the use of the Baseplate is recommended for this. However the gauge may be mounted via the three holes in the base to a paving slab for example. It is suggested that rawlbolts are used for this purpose as they provide a means of levelling the rain gauge.

Unscrew the 3 upper nylon thumb nuts and remove all the nylon spacers from the studs.

Lift off the tipping bucket base assembly to leave the metal baseplate and studs.

Fix the baseplate to level ground using the 4 pegs provided through the 4 corner holes. The baseplate may be mounted to hard surfaces like concrete by replacing the 4 supplied pegs with screws and rawlplugs.

For temporary mounting on hard surfaces use some bricks or heavy weights on the four corners of the baseplate (the height of the weights should be kept as low as possible to cause the minimum interference with the aerodynamics of the rain gauge).

Refit the tipping bucket base assembly.

Refit the nylon spacers over the 3 studs.

Loosely screw on the 3 nylon thumb nuts.

MetPak RG User Manual Last Change © Gill Instruments Ltd 12 February, 2013 Page 17

Leveling the Base Assembly

Upon completion of the above adjust the 3 leveling thumb nuts under the tipping bucket to align the spirit level bubble to within the centre circle.

Now tighten the upper 3 thumb nuts ensuring that the spirit level bubble remains within the centre circle.

NOTES:

Ensure that the Foam insert under the tipping bucket is removed before re-fitting the funnel.

No two rain gauge designs are ever likely to produce identical results, and identical rain gauge can give slightly different catches even when sited close to each other.

Customers with 2 or more sets of equipment must not swap around rain gauges with MetPaks without using MetSet to change the calibration figure.

This section provides an overview of the operation of the MetPak RG. For more detailed information about any of the steps, use the references to other sections of this manual.

3.1 Start Guide

Decide how you are going to connect MetPak RG to your PC or communications network. MetPak RG supports the following options:

 USB connection using Gill’s RS232 to USB 1.8M configuration cable

(includes integral 5V power supply) compatible with MetSet. To order, contact your dealer quoting part number: 1723-10-051).

NOTE. You could use an equivalent RS232-USB adapter such as EasySynch RS232 to USB adaptor.

 RS232 connection using standard cable and PC COM port. Separate

5V to 30V dc power supply also required (compatible with MetSet).

 RS422 using RS232 converter (compatible with MetSet).

 RS485 2 wire point to point (not compatible with MetSet).

 SDI-12 connection (note SDI-12 is not compatible with MetSet

Software).

NOTE. MetPak RG is pre-configured for RS232 communication (factory setting). If you want to use an alternative communication protocol, you will need to set up the unit using an RS232 connection (with an appropriately wired cable), change the setting, shut the unit down, attach a cable for the new communication type, and then restart the unit.

Unpack MetPak RG. Check that you have the following:

 MetPak RG unit (Part No.1723-3B-2-111).

 Rain Gauge and four pegs.

 Gill MetView and MetSet Software and Manual supplied on the CD.

If any parts are missing, please contact your dealer.

1. Open the connection box by unfastening the four retaining screws. Locate

the connector: J5 (see Page 9, Figure 3). Carefully pull the connector block from its pins.

2. Prepare the communications cable by stripping the wires to a length of 8mm.

Feed the prepared cable through one of the two available ports on the side of the connection box (please refer to the 2nd NOTE on Page 8).

3. Connect the cable to J5 as required for your chosen communications

method.

4. Carefully press J5 onto its circuit board pins.

5. If connecting the 6 Metre Rain Gauge cable to the Digital Input, strip cable

wires, (if necessary) and connect to connector J8 in the hub box.

4.2 Servicing

In the event of failure, prior to returning to an authorised Gill distributor it is recommended that:

 All cables and connectors are checked for continuity, bad contact,

corrosion etc.

 A bench test is carried out as described in the next section.

Contact your supplier if a fault persists.

4.3 Bench Tests

Carry out MetPak RG bench test as follows:

1. Connect the MetPak RG unit to the host PC and power supply, using a known working test cable.

2. Check that the unit is correctly configured by going into Set Up mode (see page 40).

3. Check for normal output data, and that the Status Code is OK – 00.

4. If the status code is other than 00, refer to Table 12 for a list of status (error) codes.

5. Use an office fan or similar to check that the unit is sensing wind, turning the unit to simulate changing wind direction and to check that both axes are functioning.

6. Check for output changes in temperature and relative humidity sensor (the fan will also cause small changes in these properties).

Contents

Carry out Rain Gauge tests as follows:

1. Connect a DMM to measure resistance between the 6 Metre cable clear and black wire connections.

2. If the unit is assembled slowly pour in water to see make and break connections and momentary readings (of 47 ohms) in each tip direction.

3. If the unit is disassembled gently move the tipping bucket arm to the upright position and read the DMM resistance between the clear and black contact wires is close to 47 ohms. As the arm moves away from the upright position to a rest position in either direction the resistance should change to Greater than 1M ohms (open circuit).

Contents

5. Maintenance

5.1 Wind Sensor (WindSonic)

If there is any build-up of deposits on the unit, it should be gently cleaned with a cloth, moistened with soft detergent. Solvents should not be used, and care should be taken to avoid scratching any surfaces. The unit must be allowed to defrost naturally after being exposed to snow or icy conditions, do NOT attempt to remove ice or snow with a tool.

There are no moving parts or user-serviceable parts requiring routine maintenance.

Opening the unit or breaking the security seal will void the warranty and the calibration.

5.2 UV Shield (RM Young Model 41003)

5.3 HygroClip for Temperature, Humidity and Dewpoint

(Rotronic Model HC2-S3)

For extreme environments such as maritime installations, chemical plants or other areas of high pollution or contamination, Gill highly recommend replacement of the temperature and humidity probe filter every 6 months to ensure proper performance. Corroded, discoloured or clogged dust filters should be replaced.

If the filter is not replaced it is very likely you will see elevated humidity levels with time and if this is allowed to develop for a longer period of time it can lead to permanent damage on the electronics of the temperature probe due to the very high moisture content and corrosive effect of the pollutant or salt.

Rotronic Temperature and Humidity filter replacement:

The Rotronics polycarbonate dust filter screw-on cap is available from:Gill Instruments Part Number 1723-PK-025 (2 filters). Rotronic Part Number NSP-PCW-PE (1 filter). If you need to replace the dust filter cap, carefully unscrew it and withdraw carefully avoiding contact with the Temperature and Humidity circuit board. When re-fitting the filter cap, ensure the circuit board connections are not bent.

Consideration should be given to an annual calibration check of the HygroClip sensor by the manufacturer.

If you are replacing the whole cartridge, unscrew the metal ferrule and return the probe to Rotronic for calibration. Refer to the Rotronic Website for more details:

http://www.rotronic-humidity.com/content/meta/kontakt.php

NOTE. If you return the sensor to a HygroClip supplier for exchange, please request that the return unit has the dewpoint feature enabled.

5.4 Barometer (on Hub PCB)

The Barometer device is maintenance-free, however, if required observe the following with regard to the central Hub box screw cap Gore-Tex® filter.

Pressure Sensor Filter Replacement:

There is a small venting filter for the pressure sensor of the MetPak located on the 'Hub' box lid which ensures proper conditions are present in the MetPak 'hub' box for pressure measurements without allowing any moisture or other damaging pollutants into the box.

This filter is made from Gore-Tex

material and is designed to last a long time

without replacement, however, Gill do recommend that this filter is replaced every 24 months to ensure proper operation of the pressure sensor and to keep the electronics inside the 'hub' box dry.

If you do not replace the filter every 24 months you may start to see elevated or erroneous readings of the pressure sensor with time and this behaviour can be

corrected by replacement of the Gore-Tex® filter unit. The Gore-Tex® filter kit is available from:-

Gill Instruments Part Number 1723-PK-024.

To replace the filter, unscrew the 4 screws retaining the hub box lid. Remove the existing Gore-Tex filter and M12 Nut. Fit and secure the new filter with the nut provided. Re-fit the 4 lid screws.

Should you be uncertain as to how often you should be replacing the filters for your application or if you wish to discuss this in more detail please contact Gill support and we will be able to provide a recommendation for you.

5.5 Rain Gauge

Maintenance periods are site dependant but periodic maintenance every 2-3 months should be considered.

To ensure reliable and accurate measurements, we recommend that the following checks are carried out at each visit to the rain gauge.

Please note that if the gauge is still connected to a data logger, and logger is operating care must be taken to avoid tipping the bucket when carrying out the following operations.

1. Inspect the funnel and filter for any damage or blockage. At certain times of the year leaves may have accumulated in the funnel, dirt and dust can also block the filter preventing or reducing the flow rate to a slow drip to the buckets beneath. The leaves can easily be removed from the funnel.

2. Unscrew the 3 nylon screws securing the funnel to the case assembly and remove the funnel.

3. Remove the end cap from the filter tube; remove the gauze filter material carefully.

End Cap

Gauze

Contents

4. The external plastic funnel surface should be cleaned with clean water and a sponge; this will generally remove any green Verdi Gris should this have been allowed to grow.

5. Chemicals/detergents should not be used if the water is to be collected for later analysis. Otherwise mild detergents can be used if required.

6. The internal funnel tube that directs water to the tipping buckets may need cleaning, use a pipe cleaner or small nylon bristle wire brush or similar part to insert into the pipe to clean it

7. Clean or replace the gauze filter into the filter tube and replace the top cap (see spare part 1723-PK-114).

8. Remove and clean any dirt from the tipping buckets, being careful not to tip the bucket should the rain gauge still be logging.

9. Check that the gauge is still level. It is possible for the gauge to become tilted as a result of small ground movements, vandalism etc.

10. There will be times when for one reason or another the rain gauge will be not logging or will be disconnected from the logger, during these times it is a good idea to check the balance arm of the bucket for stiffness. The easiest way to do this in the field is to try and balance the bucket in its centre position, it should be very difficult if not impossible to achieve this, if the bucket balances easily then examine the bucket closely for any dirt or wear on the pivot pin and bucket tubes. Any wear will require the unit to be repaired/replaced.

11. There is a drain hole at the base of the instrument with a gauze covering that might require periodic cleaning. Carefully lift out the tipping bucket assembly to gain access to the drain hole for checking/cleaning.

12. Carefully re-assemble the Rain gauge parts. When assembling the funnel to the base assembly check that the internal funnel does not foul onto the tipping bucket. This can be checked by pouring in water and checking the bucket tips or if the whole assembly is not fixed in position by gently rocking the bucket and listening for the bucket to tip.

13. Internal parts require no lubrication.

NOTES

MetPak RG is supplied with a matching Rain Gauge and its tip calibration factors will have been pre-programmed into the MetPak hub box. If a replacement or recalibrated Rain Gauge is used then the Hub box will need programming using MetSet with the new tip calibration factor if this has changed.

Calibration figures can be seen on the labels inside the Rain Gauge on the underneath of the bucket and adjacent to the tip assembly.
