TigermagEP
Obstructionless
Electromagnetic Flowmeter
Description
The TigermagEP is a microprocessor based
electromagnetic flowmeter designed to measure the
flow of conductive liquids in full pipes. This
datasheet applies to the Hot-Tap Removable
Electrode Option.
Installation
Meters with the Hot-Tap option are installed in
pipelines in tthe same fashion as standard
meters. Added space is required around the
meter, however, to allow for space to remove
the electrodes. Below are the recommended,
and minimum, distances for centerline of the
meter to the closest wall or other obstruction.

Features
Sparling's Hot-Tap electrode design has several key
features:
1)
There is no interruption of flow or
depressurization of the line required
during electrode replacement or
maintenance.
2)
Sizes available from 6" - 54"
3)
Liners: Hard Rubber, Polyurethane,
Ceramic, FEP/PTFE and Polyurethane liner
for potable water certified to NSF61.
4)
No special tools required - removal can be
easily performed with standard tools.
Removal/Insertion of Electrodes
Removing Hot-Tap electrodes takes only a few
straightforward steps:
1)
Remove port cover by removing 6 bolts.
2)
Remove the electrode cable from the top of
the handle by removing the screw.
3)
Loosen the thumbscrew which releases the
electrode assembly and allows the black
electrode handle to be pullled out
approximately 4" to its "STOP" position.
4)
Turn the shut-off valve handle clockwise to
close the ball valve and isolate the electrode
from the process fluid.
5)
Remove the electrode assembly with a
crescent wrench.
To insert, follow the steps in reverse.
