1. Product overview

Thank you for choosing the ULP Ultrasonic Anemometer from Calypso Instruments. This ULP is the first model of our generation II, representing an important technology breakthrough condensing an extensive R+D investment:

• Both shape and firmware have been enhanced for an improved rain performance, being this point key for static applications such as weather stations.
• Mechanical design has been revamped making the unit more robust and dependable.

We feel very proud to release a unit that requires under 0,4 mA of power at 5V, sampling at 1Hz. Different output options available: RS485 and UART/TTL.

Applications for the ULP are the following:

• Weather Stations | Drones
• Temporary Scaffolding and construction | Infrastructures and building | Cranes
• Spraying | Irrigation | Fertilizing | Precision Agriculture
• Smart Cities | Wild fires | Shooting | Scientific

2. Package content

The package contains the following:

• Ultrasonic Wired Wind Instrument + cable 2 meters for connection
• Serial number reference in the back of the packaging
• Quality control reference in the same place as the previous one. (Both shown in the Image 1)
• User Quick guide at the back of the packaging and some more information useful for the customer.
• Connection instructions picture including at the box package.
• M4 headless screw (x6)
• M4 screw (x3)

3.4. Sensors

• Ultrasonic transducers (4x)
• Sample rate: 0.1 Hz to 20 Hz

The ULP has been designed to avoid any mechanical parts to maximize reliability and minimize maintenance.

The transducers communicate between themselves two by two using ultrasonic range waves. Each couple of transducers calculates the signal delay and gets information about both, wind direction and wind speed.

3.5. Wind information

Wind speed

Range: 0-45 m/s

Accuracy: ±0.1 m/s at 10m/s

Wind direction

Range: 0-360°

Accuracy: ± 1°

3.6 Easy mount

3 x M4 lateral female thread

3 x M4 inferior female thread

Lateral and inferior female thread. It can be mounted either on a plate (inferior screws) or on a tube (lateral screws).

North mark position

Make sure the north mark is perfectly aligned.

Mounting accessories

Pole mount up to 52 mm

Flat mount

Adapter to Poles up to 39mm

3.7. Firmware

Upgradable via RS485 or UART/TTL

ULP is engineered to be a robust device with minimal downtime. This new shape has been designed for optimum water spillage which implies lower probability of ice formation. Frost might affect measurements if it blocks the wave path.

The input wires are protected by Transient Voltage Suppression (TVS) diodes. Also, the instrument body is built in Polyamide.

3.8. Limitations

The input wires are protected by Transient Voltage Suppression (TVS) diodes. Also, the instrument body is built in Polyamide.

3.9. Quality control

Every single unit is automatically calibrated on a wind tunnel. A Q/C report for both module and angle is generated and kept in our files. Standard deviation is checked to warranty that each unit is been calibrated to the highest standards.

4. Configuration options

baudrate: 2400 to 115200 (8n1) bauds

output rate: 0.1 to 20 Hz.

output units: m/sec., Knots or Km/h.

The Ultrasonic ULP can be set up by using a special App made by Calypso Instruments.

In order to use the APP you should download the following documentation:

Ultrasonic ULP configurator.exe

5. General information

5.1. General recommendations

As described previously is important to understand that the unit can be mounted directly on a pole or using a flat bracket. In either case make sure the north mark is perfectly aligned.

Then install the sensor in a location free from wind perturbation.

Other important aspects

• Do not try to modify by any case the unit.
• Avoid touching the transducers
• Do not modify/customize the surface of the unit.

If you have any questions or doubts, please contact directly with us. We will be glad to assist you in any time.

5.2. Maintenance and repair

Thanks to the mechanical simplicity the ultrasonic does not require mechanical maintenance.

Transducers must be kept clean and aligned. Impacts or incorrect impulsive handling may lead to transducers misalignment.

The space in between the transducers and its reflection surface must be empty and clean. Dust, frost, water, etc... will make the unit stop working. Rinse with fresh water and let it dry.

5.3. Warranty

Warranty is void in case of norfollowing the instructions of use, repair or maintenance without written authorization. Every Calypsoproduct offers a 2-Year Performance Warranty.

Calypso Instruments shall not be liable for any damages arising out of:

• Exposition of the Ultrasonic at temperatures out of the range stated above.
• Transducers misalignment or damage duto external impact.
• Solarcell damagedue to removing the protecting film.
• Geometry changes on the flow channel due to external actions.
• Use inappropriatevoltages.
• Do not installed the ultrasonic as stated above which causes damage on the ultrasonic.

You can return unopened items in the original packaging within 30 days of your purchase with proof of purchase. Upon receipt of the returned item, we will fully examine it and notify you via email, within a reasonable period of time on the status. If we decide a return is appropriate, we will refund your purchase price and a credit will be applied to your original method of payment.
