A velometer is a device used to measure the speed of air in a given area. Often, the amount of air flow in the environment is directly proportional to the degree of corrosion experienced by a metallic structure and the drying rate of protective paints that are used to coat such structures.

What is a velometer?
- Definition from Corrosionpedia What Does Velometer Mean? A velometer is a device used to measure the speed of air in a given area. Often, the amount of air flow in the environment is directly proportional to the degree of corrosion experienced by a metallic structure and the drying rate of protective paints that are used to coat such structures.
What is an Alnor velometer used for?
The Alnor Velometer is a direct reading instrument for measuring air ve- locities. The Velometer set consists of the meter, velocity and static pressure Range Selectors, measuring probes and connecting hoses. The Velometer is basically an air flow meter reading in feet per minute (or meters per second).
Why do they use piezo velometers for frame measurements?
To take frame measurements they use piezo velometers. These measurements are taken to trend the frame movements and to look for imbalance. I was told velometers are used so that data isn't lost integrating from acceleration to velocity. Somehow this doesn't make sense to me.
Do you use velometers on your agitator?
I have a few velometers installed on an agitator where accelerometers show ski slopes due to sharp pressure pulses. Indeed also caused by a recip. The ski slopes with the accellerometers make the overall values worthless to monitor on. The velometers give a nice spectrum, an therefore a valuable overall value.

What is an anemometer used for in HVAC?
Is anemometer a sensor?
To measure the energy borne of these winds, scientists mostly rely on wind sensors called anemometers. Anemometers are devices used by meteorologists to measure wind speed. Several wind sensors – anemometers exist to measure wind speed.
What is Kata thermometer?

What is a velometer?

What is a vane anemometer?
The vane anemometer is a classic wind speed meter which is now very commonly used, not only outdoors, but also indoors. Easy handling makes it possible to measure airspeed quickly using the impeller anemometer. measurement of airspeed, volume flow and temperature.
What is a voltmeter?
A voltmeter is one of the most useful devices for home electrical testing, when used correctly. Before using a voltmeter for the first time, learn how to set the device correctly, and test it out on a low-voltage circuit such as a household battery. This article describes how to test for voltage.
How to read a voltmeter?
1. Find a voltage scale on the needle's dial. Choose one that matches the setting you chose on your voltmeter's knob. If there is no exact match, read from a scale that's an easy multiple of the setting. For example, if your voltmeter is set to DC 10V, look for a DC scale with a max reading of 10.
How many test leads does a voltmeter have?
Insert the test leads. Your voltmeter should come with one black and one red test leads. Each has a metal probe on one end, and a metal jack on the other that slots into the holes in your voltmeter. Plug in the jacks as follows: [4]
What does mv mean on a voltmeter?
mV stands for millivolt ( 1 / 1000 V), sometimes used to indicate the lowest setting. Insert the test leads. Your voltmeter should come with one black and one red test leads. Each has a metal probe on one end, and a metal jack on the other that slots into the holes in your voltmeter.
How to test voltage?
1. Set your device to measure voltage. Most voltage-measuring devices are actually multimeters, which can test several aspects of electrical circuits. If your device has a knob with several settings, set it to one of the following: [1]
How to test voltage of AC circuit?
To test the voltage of an AC circuit, set the knob to V~, ACV, or VAC. Household circuits are almost always Alternating Current. To test voltage of a DC circuit, choose V–, V---, DCV, or VDC. Batteries and portable electronics are typically Direct Current. Choose a range above the max expected voltage.
What is a velometer?
A velometer is a standard ICP-type acceleroemter with an analog integration circuit inside the case that provides a voltage proportional to acceleration. The frequency range is typicallly less than an accelerometer, because of the integrator cicuit. I believe the accuracy is similar.
Why use piezo velocity transducer?
You use a piezo-velocity transducer for several reasons, limitation of noise, no-lag velocity signal, limitations of diagnostic equipment, and maybe some other reasons. One, you can get a velocity signal without integrating an acceleration signal in a monitoring system.
Why use piezo velocity?
Another reason for using the piezo-velocity setup is that the velocity signal has virtually no transducer phase lag. If you choose to use a moving coil transducer, then the transducer has a frequency dependent lag. Some monitoring systems are not set up to handle transducer lag.
What is the DCS reading on a Bently monitor?
If it is a Bently system, the DCS reading is almost certainly going to be in velocity 0-Pk. Do you have your CSI set up to read velocity in rms? If so your CSI will likely read about 70% of the monitor reading assuming that the vibration is mostly running speed.
Which is better: moving coil velocity probes or amplification?
If you go to the nitty gritty lo signal you should look at HOW more output is produced. Piezo material produce noise, if you just make higher amplification and not higher raw signal you also amplify the noise. Moving coil velocity probes are better to amplify as the noise produced in the sensor is much smaller.
Does vibration have more velocity than acceleration?
I was simply comparing the values of an acceleration or a velocity signal. I was attempting to point out that in the lower frequency ranges, for a given vibration, you have "more" velocity signal than acceleration. As many of us have studied in classes, acceleration tends to attenuate lower frequencies and accent higher frequencies, displacement is opposite, and velocity is more even across a wide band. This means that at lower frequencies, you are trying to measure a naturally smaller acceleration causing the signal to be smaller.
Is the Velomitor a Ge?
Velomitor® is trade marked by GE. Other than that it is an integrally integrated accelerometer. Spell it differently, and you are probably ok. Marketing stuff.
What is an intervalometer?
An intervalometer is a device that plugs into a camera and controls how often, how long and how many shots are taken. Models vary from manufacturer to manufacturer but they all serve the same purpose. Think of it as the old remote blub plunger on steroids. The Canon model TC-80N3 pictured at right is indicative of many models available today.
How many frames can an intervalometer take?
Number of shots to be taken, selectable up to 99 frames. The intervalometer can be used for more than just shooting time lapse films. Other uses include: Shooting images for a stacked composition, such as star trails photos. Hands free long shutter speeds for blurred action.
