Generally, thermal mass flow meter can be installed vertically, horizontally or at any angle but requiring less straight pipe to make sure the flow from upstream is smoothly. User need to make sure the 10 pipe diameter lengths upstream and 5 pipe diameter lengths downstream. Installation Requirements

1) Pipe upstream and downstream lengths must be sufficient, measure, check. 2) Pipe I.D. and O.D. must be measured correctly 3) Meter must be ordered for correct pipe sizes (note: this is step 3) 4) Order a flow straightener if U.S. distances is insufficient 5) Surest installation is to order a “flow tube” to fit into your pipeline

Most manufacturers claim that their Coriolis flow meters are not adversely affected by installation effects. As such, they should not require large lengths of straight length pipe work upstream and/or downstream of the flow meter. However, compliance with the manufacturer’s guidance is necessary. This guidance can vary depending on flow tube

Typical recommendations suggest 35 straight pipe diameters upstream and 5 straight pipe diameters downstream. If you find that you do not have sufficient upstream straight run, some manufacturers allow for K factor corrections that could reduce this requirement.

The general guidelines suggested by manufacturers of turbine flow meters are 15-20 straight pipe diameters (inclusive of the strainer) straight pipe runs 

As a rule of thumb, most manufacturers recommend a minimum of “20 times the pipe diameter” downstream of a 90-degree bend. For some exceptions

Note: in no case does a flowmeter installation automatically require a 1D of straight pipe length after the meter. U.S. = upstream. D.S. = downstream.

In reduced straight run installations, the meter may not meet accuracy specifications. Reported flow rates will still be highly repeatable. 3.3 Flow direction. The sensor should be mounted so that the arrow points

Upstream/downstream piping length To ensure specification accuracy over widely varying process conditions, install the sensor with a minimum of five straight pipe diameters upstream and two straight pipe diameters downstream from the electrode plane. See Figure 1. This procedure should adequately allow for disturbances created by

The following diagrams describe the recommended minimum straightway lengths of some types of pipe. The straightway length should be as long as possible while the room is sufficient. Without the. consideration of other factors, the recommended minimum straightway lengths are: front upstream length: 20×DN. back downstream length: 5×DN.

For upstream and downstream lengths equal to one half the values shown, add 2 percent to the accuracy value. — Any flow conditioner shall be installed in the straight length between the primary element and the upstream distance, or the fitting closest to the element. The straight lengths between

1, 2, and 3 are respectively the front, behind and by-pass valves and 4 is the flow meter. L≥10D and L>=5D are respectively front and behind pipelines whose lengths are larger than 10 and 5

Install the meter so that the flow direction arrow on the sensor case matches the actual forward flow of the process. (Flow direction is also software-selectable.) 2.2 Best practices • There are no pipe run requirements for Micro Motion sensors. Straight runs of pipe upstream or downstream are unnecessary.

The desired upstream straight pipe length is 1000mm. Downstream: allow a minimum straight pipe length at least 5 times the internal diameter of the pipe. For example, with the 50mm
