Devices for treating, sensing, or otherwise acting upon fluid

An assembly for diverting liquid flowing at a first rate through a conduit, the assembly comprising:

• a. a housing (i) defining a volume of substantially greater width than height and (ii) comprising a feeder port and a liquid flow obstruction;
• b. an inlet configured, in use, to permit liquid to flow from the conduit into the housing so as to effect the diversion;
• c. an outlet configured, in use, to permit liquid to flow from the housing to return to the conduit, the volume defined by the housing forming part of a low-flow region in which the diverted liquid flows at a rate less than the first rate;
• d. a chemical feeder communicating with the feeder port;
• e. a first port;
• and
• f. a flow sensor communicating with the first port;
• and in which at east a portion of the flow sensor extends within the inlet.

A method of diverting liquid flowing at a first rate through a conduit, comprising:

• a. providing a housing (i) defining a volume of substantially greater width than height, (ii) having an exterior surface, and (iii) comprising (A) a feeder port that extends to the exterior surface so as to be accessible externally of the housing and (B) a liquid flow obstruction;
• b. causing liquid to flow from the conduit through an inlet, of fixed size and proximate the liquid flow obstruction, into the housing so as to effect the diversion;
• c. permitting liquid to flow from the housing through an outlet to return to the conduit, the volume defined by the housing forming part of a low-flow region in which the diverted liquid flows at a rate less than the first rate;
• and
• d. attaching a chemical feeder to the feeder port.
