Remote fluid sampling

A remote fluid sampler for sampling fluid, such as oil, from machinery, said sampler comprising:

• an inlet and an outlet port via which said sampler is arrangeable in fluid flow communication with said machinery, a fluid circuit defined between said inlet and outlet ports;
• a 4-way diverter control valve configured to control a direction of fluid flow along such fluid circuit;
• a fluid meter configured to capture a metered dose of fluid from said fluid circuit;
• a normally-open (NO) control valve arranged in parallel with a normally-closed (NC) control valve to regulate dynamically fluid flow through the fluid circuit;
• a plurality of check valves arranged to regulate passively fluid flow through the fluid circuit;
• a sampling port configured to receive a sampling reservoir for receiving a metered dose of fluid;
• and
• a controller arranged in signal communication with the fluid meter, 4-way diverter and control valves and configured to perform a user-configurable control regime comprising:
• i. a flush cycle by selectively controlling the 4-way diverter and control valves to define a first fluid path along a portion of the fluid circuit which flushes the fluid meter and bypasses the sampling port;
• ii. a meter cycle by selectively controlling the fluid meter, 4-way diverter and control valves to define a second fluid path along the fluid circuit which allows the fluid meter to collect fluid from the fluid circuit and thereafter dispense such a metered dose of said collected fluid to the sampling port;
• wherein the sampler facilitates flushing of fluid through the fluid circuit to allow collection of a homogeneous fluid sample from the machinery, in use.
