4-1 : Confirmation before start-up
Introduction
Before you start up the instrument, confirm the following items. Numbers in
parentheses indicate the chapter to refer.
(1) Confirm that the electromagnetic flowmeter is installed correctly in the pipes
(Chapter 2 : Instrument installation).
(2) Confirm that the electrical wiring is correct (Chapter 3 : Electrical wiring).
(3) If communication is required, confirm that the communication equipment is wired
correctly (Chapter 3 : Electrical wiring).
(4) Fill the electromagnetic flowmeter detector with a fluid and reform zero
adjustment in a static state (Chapter 5 : Operation using the data setting device).
(5) Confirm that there is no leakage at the joint of the electromagnetic flowmeter’s
detector (Chapter 2 : Instrument installation).
(6) Confirm that the electromagnetic flowmeter detector is filled with water and there
are no stagnant bubbles.
(7) Turn on power and warm up for 30 minutes.
(8) Confirm whether the settings of the data sheet inserted in the converter have been
setup and configured. If there is need to change settings to meet your usage,
change them using the data setting device or the like.
(9) For the accurate flow measurement, verify the zero point value in each excitation
current (Manual zero1, manual zero2, and manual zero3) by using manual zero
function, if the normal flow velocity is less than 0.3 m/s (0.98 ft/s).
~Note •
If the detector is not filled with water or many bubbles have
adhered inside, the indication may not reach zero flow rate. In
such cases, make a flow of water once to ensure that the detector
is free of bubbles and filled with water.
•
With incorrect grounding, the indication of flow rate may
fluctuate largely. In such cases, check the grounding condition.
