Clamp on Flow meter

I need model for  a clamp on ultrasonic flow meter , that is battery powered

  • I think that the Emerson team and folks here will need a lot more information about your measurements needs to be able to help you. Do battery powered ultrasonic meters exist? Sure. But, they vary wildly in terms of size and capabilities.

    What is your fluid? How fast is it moving? What size of pipe? How long do you need to be able to make a measurement? How accurate does your measurement need to be?

    I assume you don't have power available where you are trying to make the measurement, or do not need the measurement for long (checking multiple locations in the field?). If there is not be a readily available solution for what you are considering, would an external battery pack suffice? There are plenty of 120VAC and 24 VDC UPS units that could be portable enough to provide power for an instrument without an internal battery.

    You will be hard pressed to find a battery powered clamp on USM.  The only USM that exist right now that are battery powered are small (2-6 inch) units that are made by Sick, have wetted transducers that have very short path lengths and intended as rotary meter replacements.  The power required by a clamp on USM to get through the pipe and the product would kill a battery in a very short period.

    Thank for the information. I will have to change the design since the meter is for 24 inches pipeline. Also, I want a non invasive device and the there no available power supply. I'm considering a solar powered if its available.
  • If don’t have any power on site your best bet would be a solar panel and battery array.

    A quick online search of portable / battery powered flow meters does turn up models from various manufacturers, but many are for smaller pipelines (I did find one can handle up to a  120" diameter). The one's I have found so far would only be able to handle 10 hours of operation before the battery needs recharging. If you want this to be a permanent installation, then I agree a combination of solar power charging a battery pack would probably be a better bet if the environment permits.

    Have you considered how do you plan to get data out? You should look into systems for either recording (onboard memory?) or transmitting (wireless?) the data, or also investing in a similarly compact / portable digital recorder that could be powered off the same solar / battery system.
