celiometer
A pachymeter is any of a group of instruments which are used to measure the thickness of something.
The answer is e.g rain gaige/ windvane/ barometer/ windmill e.t.c
In weatherwhat is used to see cloud patterns and movements?
Yes the word cloud is a noun. It can also be used as a verb.
There are many different instruments which are used to measure different aspects of the weather: wind speed, wind direction, pressure, temperature, humidity, precipitation, cloud cover, etc.
Cloud cover is usually given as a percentage, there is no unit of measure.
There are instruments called Ceilometers which can measure cloud height and cover, but they're not especially accurate for cover (they are quite good for cloud height, especially at night) as a cloud can sit over the instrument and give a false reading. Also, unless cloud passes over them they give a false negative. The best instrument for measuring cloud cover is a trained Mark I eyeball (or two)Read more: What_instrument_is_used_to_measure_clouds
An Okta is a measurement unit used to describe cloud cover over a defined area. In aviation 10% cloud cover is considered one peg up from clear to a few clouds, mainly scattered.

They are surveying instruments used to measure angles.
Some test instruments used in electronics are:Multimeter - Used to measure voltage, ampere and resistanceOscilloscope - Used to measure frequency and oscillations
The instruments used to measure the conditions of the upper atmosphere is a Radiosonde, Radar, Weather Satellites, and Computers.
A ruler, a yard stick, and a tape measure can each be used to measure length. There are other instruments, but these are probably the most common.
To measure various physical quantities, different instruments are used based on the type of quantity being measured. Here are some examples: Length: Measured in meters (m). Instruments used to measure length include rulers, tape measures, and calipers. Mass: Measured in kilograms (kg). Instruments used to measure mass include balances and scales. Time: Measured in seconds (s). Instruments used to measure time include clocks and stopwatches. Temperature: Measured in degrees Celsius (°C) or degrees Fahrenheit (°F). Instruments used to measure temperature include thermometers. Electric current: Measured in amperes (A). Instruments used to measure electric current include ammeters. Voltage: Measured in volts (V). Instruments used to measure voltage include voltmeters. Frequency: Measured in hertz (Hz). Instruments used to measure frequency include oscilloscopes and frequency counters. Pressure: Measured in pascals (Pa). Instruments used to measure pressure include barometers and manometers. There are many other physical quantities that can be measured, and different instruments may be used depending on the specific quantity and the required precision of the measurement.
