Low Flow Meter
Low Flow Meter
(OP)
To keep the jurisdiction happy, I need to measure flow either going into or coming out of a large septic tank. The flow is going to amount to a few to several hundred gallons per day--not much. All the meter guys say the accuracy goes to he11 at low flows. Does anyone know of an inline flow meter that would be accurate at low flows?

Thanks.

Howeveer, you will have to install the meter such that the metering point is full of water at all times.

z8e, if you find one that is suitable, I would appreciate your posting the info. So far, I haven't found one.

It is common practice to install multiple water meters. You can have one meter for the sanitary service and a second water meter for irrigiation purposes.
You do not have to pay the sewer charges for the water used on the irrigation meter.

An effluent meter would be the fairest way for both the utility and my client.

Assume couple thousand HCF loss is -
2000 * 100 CF *7.48 gal/CF = 150,000 gallons
Is that correct? your additional water cost is only $150 per year?
There are gravity flow meters available with that accuracy. However, the meters are for larger flows (greater than 15 gpm) and larger diameters (greater than 12") with that accuracy
Again, you would be best served with a mag meter. Magmeters have that accuracy.
