If you want to know more about our new ULP Ultrasonic Wired Mini wind meter, please keep reading or visit our website www.calypsoinstruments.com
Product overview
Thank you for choosing the Ultra-Low-Power Ultrasonic Wired Mini wind meter from Calypso Instruments. This wind sensor is the first model or our generation II, representing an important technology breakthrough condensing an extensive R+D investment:
- 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: UART/I2C.
Package content
The package contains the following:
- ULP Wired Mini Wind Instrument plus 2 meter (6.5 ft) cable for connection.
- Serial number reference on the side of the packaging.
- A quick user guide on the back of the packaging and some more useful information for the customer.
- M4 screw (x3) ****

Sensors
- Ultrasonic transducers (4x)
- Sample rate: 0.1 Hz to 10 Hz
The ULP Wired Mini 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 pair of transductors calculates the signal delay and get information about both wind direction and wind speed.
It can be mounted either on a plate (inferior screws).
- Easy mount – 3 x M4 base female tripod thread UNC 1/4” – 20
Mounting Instructions:
The ULP Wired Mini has a small circle on the outside of the main body which is
called the north mark. The ULP Wired Mini should be mounted with the north
mark facing the true north.
- Firmware Upgradable via UART/TTL
Product Material
The ULP Wired Mini is engineered to be a robust device with minimal downtime. Frost, rain or snow might affect measurements if it blocks the wave path. The input wires are protected by Transient Voltage Suppression (TVS) diodes. The instrument body is built with Polyamide.
Quality Control
Every single unit is calibrated with accuracy, following the same calibration standards for each one in a wind tunnel. A Q/C report for both wind speed and direction is generated and kept in our files. Standard deviation is checked to guarantee that each unit has been calibrated to the highest standards.
Configuration Options
The ULP Wired Mini can be set up by using a special configuration app made by
Calypso Instruments. In order to use the app, you should download
theconfigurator from our website at www.- calypsoinstruments.com. To configure
your device, connect the ULP Wired Mini via a USB to UART converter cable.
Connect all the ULP cables except for the brown cable to the converter. Insert
the USB into the computer, open the configurator app, select the configuration
wanted and follow the instructions on the screen to finish the configuration.
You will be prompted by the app to connect the brown wire at a specific moment
of the configuration. For more information, please watch the following video.

General information
General recommendations
Regarding mounting the unit, align the north mark (the circle on the side) of
the ULP Wired Mini towards the north. Make sure to install the sensor in a
location free from anything that obstructs the flow of wind to the sensors
within a 2 meter radius.
Maintenance and repair
The ULP Wired Mini does not require great maintenance thanks to the lack of
the moving parts in this new design.Transducers must be kept clean and
aligned. Impacts or incorrect impulsive handling may lead to transducers
misalignment. The space around the transducers must be empty and clean. Dust,
frost, water, etc… will make the unit stop working. The ULP Wired Mini can be
wiped clean with a damp cloth being careful to not touch the transducers.
Warranty
This warranty covers the defects resulting from defective parts, materials and
manufacturing, if such defects are revealed during the 24 months after the
purchase date. Warranty is void in case of non-following the instructions of
use, repair or maintenance without written authorisation.
Any wrongful use given by the user will not incur in any responsibility on part of Calypso Instruments. Therefore, any harm caused to the ULP Wired Mini by a mistake will not be covered by the waranty. Using assembly elements different from those delivered with the product will void the warranty. Changes on transducers position/alignment will void any warranty.
