3.7.4 Sealing the unit
The unit should be properly sealed with a sealing compound after electrical connections have
been tested according to the customer's Best Practices schedule. Some areas require a
witnessed Acceptance Test for the installed system and require that the meter run for a
predetermined length of time (approximately one to two weeks) before the unit is sealed. This
allows time to verify all electrical connections are correct, that the meter is accurately
measuring flow and that the meter meets the customer’s installation requirements.
