Follow these steps to install and operate the strainer:
1.Flush all new systems – Flushing the system before the meter has been installed is the preferred first step. Thoroughly flush the lines until the system is purged of all foreign materials. See Disassembly & Reassembly for disassembly and reassembly instructions. 2.Plan a location for the strainer in the system providing for the following requirements – Ensure there is no pipe strain imposed on the strainer or any other component part of the meter assembly. The meter and its accessories must not support the weight of the piping. Plan for enough space to allow clearance so that the strainer basket cover and strainer basket can be easily removed. |

3.Install the strainer:
(a) Install the strainer on the inlet side of the meter
(b) Bolt the strainer outlet to the inlet flanged connection of the meter.
(c) Then bolt the inlet piping to the inlet flanged connection of the strainer.
4.Check the strainer daily during the first 100 hours of operation – New or repaired piping can be the source of welding slag or other foreign material that will block or rupture the strainer screen–or until no more debris is found in the strainer.
5.Inspect and clean the strainer basket regularly – To ensure proper operation.
6.Perform regular maintenance on the strainer – Follow the steps in the Maintenance section below.
Maintenance
It's very important to follow preventive maintenance procedures to protect the strainer as well as the metering system. Foreign matter such as ice can build up inside the strainer and cause damage to the strainer and the metering system. When foreign matter builds up inside the strainer, it can cause pressure to build up inside the strainer. This pressure can cause the strainer screen to rupture. Foreign matter can then enter the metering chamber. This can cause serious damage to the meter resulting in failure of the meter.
The following strainer preventive maintenance procedures will keep your strainer functioning properly, keep strainer repair costs to a minimum, and ensure the protection of your metering system.
Newly installed or repaired systems
•Check the strainer daily during the first 100 hours of operation, or until no more debris is found in the strainer.
•New or repaired piping can be the source of welding slag or other foreign particles that can block or rupture the strainer screen.
•Once a system is cleaned out, the strainer should be checked several times every season. The frequency depends on the specific service conditions, through put and product cleanliness.
Air Eliminators & Strainers |
When an air eliminator is used with the strainer, it must be installed vertically on the strainer. |
