Due to larger pipe diameter and large flow, I need to use a wide-mouth 1-litre bottle for more accurate flow calculation!\r\r\nEven so, the fairly rough measure of 0.5 l/sec using a pipe and bottle was clearly more accurate than the timed float calculation I've been doing in previous weeks: to compare, I timed the flow in the same location using a float, and got only 0.2 l/sec, a bit less than I'd measure last week!","checked":"qc_complete","qa_notes":null,"qa_admin_notes":"","qa_admin_notes_author_id":null,"qa_admin_notes_updated_at":null,"tested_parameters":["ph","conductivity","air_temperature","water_temperature"],"photos":[],"permalink":"https://data.waterrangers.com/observations/77751","readings":[{"id":"a4f324a9-3d91-49ca-93d0-304f2dc02d77","created_at":"2025-08-22T14:47:54.883Z","updated_at":"2025-08-22T14:47:54.883Z","parameter":"ph","unit":"std_units","value":"7.66","equipment":"other_pen_type_ph_meter","equipment_limit":null},{"id":"f66be90c-aaa4-4c07-b671-fc13d277dfbe","created_at":"2025-08-22T14:47:54.894Z","updated_at":"2025-08-22T14:47:54.894Z","parameter":"conductivity","unit":"us_cm","value":"181.6","equipment":"other_pen_type_conductivity_meter_us_cm","equipment_limit":null},{"id":"4688c3a5-194b-445e-8e5c-11aa02d5a336","created_at":"2025-08-22T14:47:54.900Z","updated_at":"2025-08-22T14:47:54.900Z","parameter":"air_temperature","unit":"deg_c","value":"13.7","equipment":"stream_thermometer_water_rangers","equipment_limit":null},{"id":"85cd43e3-8120-4902-b6f3-3f41a6614a81","created_at":"2025-08-22T14:47:54.905Z","updated_at":"2025-08-22T14:47:54.905Z","parameter":"water_temperature","unit":"deg_c","value":"13","equipment":"other_multimeter_temperature","equipment_limit":null}]}
