Calculate a coolant top-up or correction.
Record liquid present, usable capacity and measured concentration. Enter target and makeup limits from your product instructions.
Fixed makeup mode calculates an addition that fits or a drain-and-replace. Balanced fill mode calculates makeup needed to reach the full mark, then checks the product-approved range you enter. Both preserve measured state and new-concentrate cost.
Follow the sourced balance examples and record limitations.

-
Identify product and instrument
Read the exact product and machine instructions for target, approved makeup, sampling and mixing. Record instrument identity and labeled range. Zero with the same mix water under the instrument instructions; check a reading at the top limit. A clipped reading can under-report concentration, which this arithmetic cannot detect.
-
Enter measured state
Enter liquid actually present and usable full capacity, plus known concentration or Brix and the exact product factor. Use liters or US liquid gallons and matching concentrate-price units. No concentration target is supplied.
-
Choose the planning job
Use fixed approved makeup correction or calculate a balanced fill-to-full mix within your product-approved minimum and maximum. Review final level, drain, premix, components, cost and warnings. Impossible and disallowed mixes stop the plan.
-
Mix and complete the record
Follow shop isolation/drain and product mixing procedures. Prepare premix with water first, then add concentrate while mixing; never add water to concentrate. A mathematical endpoint is not approval for direct addition. Mix and remeasure as instructed, then complete the dated record.
Built For
- On-target but low sump: calculate the permitted fill-to-full mix.
- Slightly rich low sump: calculate a weaker fill mix within entered product limits.
- Slightly lean low sump: calculate a stronger fill mix and concentrate consumption.
- Full or nearly full sump: identify whether a fixed approved premix correction requires space.
- Repeated US-gallon/liter maintenance records with product, measurement, approved inputs, cost and remeasurement.
Features & Capabilities
Two distinct planning jobs
Fixed makeup correction returns no correction, a fitting addition that may stop below full, a drain-and-replace, or refusal. Balanced fill derives required makeup and checks physical and entered product limits.
Brix and component accounting
Brix times the exact product factor yields concentration. Plans show liquid retained, drained and added, premix concentrate and water, existing/removed/retained/final concentrate-equivalent volumes, both units and new-concentrate cost. These are volumes, not chemical ingredient masses.
Dated sump record
Save or share active inputs and metadata. Print/export all visible values, state, warnings, product, machine, operator, date, instrument, range, mixing order and a remeasurement space. A record is not a fluid-condition or safety certificate.
