Propeller meters require continuous inspection and maintenance, which may amount to very little to very much, depending on local conditions and brands selected. Potential users should seek information from other local users before selection. In some cases of high maintenance costs and expensive water, these meters have paid for themselves in as little as 2 months on the basis of water conserved. However, in other areas where water is relatively plentiful, they have never repaid their original cost. Propeller bearing troubles are the most expensive and common problem and may be difficult to overcome except by means of a well-planned maintenance program.
Maintenance costs can be excessive if meters are used for water with sediment.
Propeller meters require a maintenance routine where bearings are replaced based on time of operation.
