It refers to the pipe wall thickness.

The main reason for the low turndown is the relation between flow and dP not being linear. Volumetric flow is based on the square root of the dP, which means that your 40:1 transmitter is really only like 7:1. Even with that the low end of the transmitter is not as accurate, most transmitter...

If you are talking about a clamp-on or bolt on USM you still need some up stream and down stream pipe diameters. There is most likely a recommended length for hfo. Have you considered Coriolis type meters they require no up or down stream length and have good turn down ratios

If the center vertical link is removed the device will not clamp when lifted. As a vertical force is applied to the top vertical member, the device starts to close and a clamping force is applied to the load being lifted. To analyze this device you would need to know the lengths of the links...

DVD that is very funny LOL

LOL A Blow computer is just a typo for a FLOW computer used to calculate the flow volume and adjust for Pressure and Temp I got some clarification on the Frequencies It is actualy 2 frequencies one gives the open collector signal and the seconed is the same frequency only out of phase...

Yes it is a 2 wave frequency proportional to flow rate, in the forward direction they are +90° out of phase and in the reverse direction they are -90° out of phase. The output type is an open collector. I don’t voltage level off hand. There is no PLC on site just the meter and a blow computer...

I have a bit of a dilemma; I have a bi directional meter, the flow output uses a quadrature Frequency (+-90 out of phase). The device that receives the signal cannot accept this signal, but two separate frequencies. Is there a device that can convert the quadrature frequency in to to separate...
