SELECTING A MOUNTING LOCATION
Install COIN elements horizontally, rotated 90° along the pipe center line, see
. This method of mounting allows for free
passage of solids and eliminates air entrapment at the transmitter connection . Other positions are acceptable provided there
is proper venting of the transmitter and differences in lead line elevations are considered . Vertical installations as shown in
may introduce a slight hydrostatic head effect, which must be considered when zeroing the transmitter . Connections
between the COIN meter and the transmitter should be 3/8 in . (9 .53 mm) tubing minimum . Use a three-valve manifold for
zeroing the transmitter .

Each flow element has an arrow indicating the required direction of flow . Failure to properly orient the COIN element may
cause improper results when using data supplied for an element that has been calibrated .
NOTES:
1. Φ =1 in./ft (80 mm/m) for water;
2...4 in./ft (60...320 mm/m for more viscous fluids.
2. Minimize all lead line lengths.
