Section 3 Operation
3-1 Pre-Start Check
After the flowmeter has been properly installed in the process, it is ready
for operation. When initiating flow, slowly open the valve to avoid a flow
surge.Bypass is a help in bringing the flow on smoothly. Avoid starting a
pump to supply the flowmeter without the use of a valve upstream of the
flowmeter
At no flow condition the indicator pointer should align with the “0” mark on
the scale. If necessary, adjust the pointer as per directions in the Mainte-
nance Section 4-3.
