The Vision Turbine Meters comply with the lead-free provisions of the Safe Drinking Water Act. Available models include meters that are:
MEASURING PRINCIPLE
The rotor is turned by the liquid force proportional to flow. A Hall effect sensor supplies pulses that can be used for digital or analog signal processing. The generated pulses are specified as a K-factor.
OPERATING PRINCIPLELiquid flow causes a bladed turbine inside the meter housing to turn at an angular velocity directly proportional to the velocity of the liquid measured. As the blades pass beneath a magnetic pickup coil, a frequency signal is generated. Each pulse is equivalent to a discrete volume of liquid. The frequency pulse is directly proportional to the turbine angular velocity and the flow rate. The large number of pulses provides high resolution. As the mass of the turbine is small, the response time is fast. It is not necessary to install a straight length of pipeline upstream of the meter. The simple mechanical construction of the Vision meter provides a long lifespan without any loss of accuracy. Pressure spikes less than the burst pressure rating do not affect the measurements.

Turbine Flow Meter, 0.26 to 6.6 GPM, Trogamid, 3/8
I have used multiple iterations of these flow meters are they are reliable and easy to configure for our needs.

Excellent little meter for low-flow applications.
A compact, well made, and very precise device. Wiring it up took about 15 minutes, and it integrates easily into any device that can measure square-wave frequency or count pulses. Very satisfied with the devices precision.

Not Plug & Play
I purchased this sensor under the assumption that I could connect in to my OMB-DAQ-2408 and read the frequency of pulses through DAQami. Although DAQami supports frequency on counter channels, this feature wasn't available for my device. After spending 10hrs screwing about and downloading DASYlab, I called customer support. They recommended I buy a 500$ signal conditioner. Reminder-- This 125$ sensor also needs an external pull up resistor because it would've been too expensive to integrate inside the device. I understand that Omega does not create these devices or any of the software but it was a very frustrating experience that could've been avoided with a better shop page.

Product Ethanol Compatibility
it is good with water but not compatible with ethanol
Date published: 2023-01-20
What range should we expect the K-factor for pulse to flowrate conversion to be (for water)? Would you recommend finding this for each flowmeter or just using a consistent value for each fluid type? Thank you.
Thank you for your inquiry. The K-factor is listed on the data sheet in both pulses per gallon and pulses per Liters and ideally for water. In the event you are using a different liquid that is not water, you will need to adjust for a new K-factor and the following equation can assist:
f = (K x Q)/60
f = Hz
K = pulses per gallon
Q = is the flow rate in GPM
