Maintenance Restrictions
As mentioned earlier, all FlowHawk flow monitors are
manufactured to meet IS standards. The monitor’s IS certification
can be voided instantly if proper maintenance and service
procedures are not followed. IETG must restrict certain
maintenance tasks to IETG IS-certified technicians.
IETG-certified technicians carefully inspect and document their
repairs of IS monitors. This inspection and documentation process
provides legal protection should the monitor's performance or safety
be in question.
