Laboratory experiments showed that the long-throated flume was an effective flow-measurement structure with simple shape, low head loss, high modular limit, high robustness and accuracy. The best side contraction rate and vertical rate was 1:3 for accurate field calibration. When designed properly,...
A Montana flume is a Parshall flume without a diverging downstream section and is used to measure open channel flow. Under free-flow conditions, the Parshall flume and the Montana flume have the same calibration characteristics, but under submerge flows, their calibrations significantly differ. Tes...
I compare the flow meter with Krohne and Siemens.I found the accuracy is higher than 0.5%.I believe you use 5 points calibration.and the price are much lower. Low Price Dn150/100mm RS485 Display Digital Industrial Liquid Waste Water Electromagnetic Flow Meter ...

These measurements were used to develop calibration relationships between the bed shear stress (which is difficult to measure directly in routine deployments) and the flume centerline flow velocity, which is routinely measured. An example of a successful deployment of the flume is presented. The ...

In the state of Utah, where several field calibration tests were performed on Montana flumes, the flume operators/owners simply use a Parshall flume lookup table to determine the flow rate. The owners assume free-flow conditions, so in this case, it is necessary that the Parshall and ...
