What is a velodometer?
Which type of measurement is done by Velometer?
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 Velometer vibration?
Velometers. Velometers are Piezoelectric type Vibration Sensors that have a Voltage Output proportional to Vibration Velocity.

What is vibration sensor?
A vibration sensor is a device that measures the amount and frequency of vibration in a given system, machine, or piece of equipment. Those measurements can be used to detect imbalances or other issues in the asset and predict future breakdowns.
What are the 10 uses of anemometer?

How do you check air flow?
Multiplying air velocity by the area of a duct allows you to determine the air volume flowing past a point in the duct per unit of time. Volume flow is generally measured in cubic feet per minute (CFM). Air velocity is measured by sensing the pressure that is produced through the movement of the air.
What instrument measures air flow?
anemometerAn anemometer is an instrument used to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind.
How does velocity sensor work?
The magnet of the velocity sensor is suspended on a membrane (spring) which moves through a coil of wire. Due to the vibration, the coil of wire moves through the magnetic field of the permanent magnet and generates (induces) a voltage signal which is proportional to the vibration (velocity).
How do you test a vibration sensor?
The output of the sensor is read using a multimeter. First, readings should be taken with no vibration. The vibration level should then be increased at a given frequency until vibration levels reach the top of the measurement range for the sensor under test.
Difference betwen a velometer and an accelerometer
Thanks for the info, We have a confusing situation here , on this particular feed pump we have a velometer mounted on the pump IB and OB bearings, connected to the control room DCS system, so we are monitoring 24/7, recently the readings started increased to 0.3ips, however our CSI 2130 says the overall vibration is 0.2 ips, our transducer was checked and verified to be good( 160 Hz at 1g).

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.
