Product overview
Thank you for choosing the ULP Ultrasonic Anemometer from Calypso Instruments. This ULP is the first model or our generation II, representing an important technology breakthrough condensing an extensive R+D investment:
- Both shape andfirmware have been enhancedfor an improved rain performance,beingthis 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
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

Wind direction
The ULP has been designed to avoid any mechanical parts to maximize
reliability and minimize maintenance.| Wind speed
Range: 0- 45 m/s
Accuracy: ±0.1 m/s at 10m/s
---|---
The transducers communicate between themsel – ves two by two using ultrasonic
range waves. Each couple of transductors calculates the signal delay and gets
information about both, wind direction and wind speed.| 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).
Mounting accessories
3.7. Firmware
- Upgradable via RS485 or UART/TTL
3.8. Limitations
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 VoltageSuppression (TVS) diodes.
Also, the instrumentbody 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 keptin our files. Standard deviation is checked to warranty that each unit is been calibrated to the hightest standards.
Configuration options
baudrate 2400 to 115200 (8n1 ) bauds
output rate: 0.1 to 20 Hz.
output units: m/scc., 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
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/customizethe surfaceof 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 alignedImpacts or incorrect impulsive
handling may leadto 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.
5.2. Warranty
Warranty is void in case of no-nfollowing the instruct ions of use, repair or
maintenancewithout written authorization.Every Calypsoproduct offersa 2-Year
PerformanceWarranty.
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 dueto external impact.
– Solarcell damagedue to removingthe 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.
