Practical guides on pond dissolved oxygen, sensor calibration and aeration control for fish, shrimp and crab farms — see what TAYKEE is.
ProductFour layers, the DO-to-VFD closed loop, offline fallback, typical deployments and clear boundaries.
FAQWhat it solves, automatic DO control, remote access, power cuts, calibration, cost drivers and how to start.
GuideThe pre-dawn trough, why pH swings alongside DO, how automatic control closes the loop and which parameters to monitor.
GuideComfortable >=5 mg/L, warning <=3 mg/L, danger <2 mg/L — with a species table, risk windows and aeration timing.
GuideRunning longer is not the same as being safe. Timing, the real cost of running flat out, and DO-based control.
GuideOptical vs polarographic burden, intervals, the correct 100% air-saturation procedure, and when to replace the cap.
GuideWhy biofilm biases readings low, how motorised wipers work, design points and a realistic maintenance rhythm.
GuideThe four-tier speed strategy, offline fallback, 15~20% VFD headroom with IP65 and realistic energy savings.
GuideNot the threshold — it is bottom-dwelling behaviour, moulting, load and algae. Includes a side-by-side action table.
GuideThree lines (≥5 / ≤3 / <2 mg/L) and a 7-species table; polyculture sets the line by the most sensitive species.
GuideManual samples are daytime snapshots; online runs 24 hours and drives the aerators automatically.
GuideStart half the aerators, watch DO climb, add the next batch — TK-R12 switches them in groups.
GuideFour cases where it pays for itself, three where it does not — by density, species value and pond count.
ProductPer-pond thresholds, one dashboard, grouped alarms; TK-R12 twelve outputs sized by current.
GuideAn oxygen budget: income barely scales with density while expenses do. Four fixes and when to cut density instead.
SizingThree-step sizing, 0.75/1.5/2.2/3.0 kW ratings, 15~20% VFD headroom and around 20% electricity savings.
GuideDevice to 4G to platform to app, what the platform does, alarm escalation and what still works offline.
SizingSensing, control, power and platform layers; probe placement and a three-step retrofit path for existing ponds.
GuideOvercurrent protection guards the motor against short-circuit and locked rotor; a Type B DC RCD guards people against shock. They are not interchangeable — with trip-time coordination and contactor vs SSR selection.
