Small specialist tools for a quick calculation check on site — free, no sign-up. Each tool explains what the result is based on and points to the related area when the problem goes beyond a calculator.
Converts a 4–20 mA signal to volumetric flow on a square-root scale (orifice / DP measurement), with low-flow cut-off, a breakpoint table and a chart.
For loop checks, calibration, or finding out why the flow in the control system doesn't match reality.
Linear conversion between current, percent of range and the transmitter value (bar, °C …) both ways, including negative and reverse ranges.
For loop checks, commissioning or checking the scaling in the PLC.
°C ↔ Ω for Pt100 and Pt1000 — practical from a table or exactly per IEC 60751 (Callendar–Van Dusen), −200 to 850 °C.
When checking a temperature input, simulating with a resistor or finding out why a temperature in the system doesn't match.
°C ↔ mV for type K and J thermocouples per NIST ITS-90, with optional cold junction compensation (CJC).
When checking a thermocouple input, simulating with a voltage source or finding out why a temperature reading is off.
Converts 15-minute interval energy to average demand (P = 4 × E) and evaluates a series of intervals — peak, mean and a comparison with your own limit.
When you want to understand how meter data turns into peak demand, before looking at optimisation or an investment.
Compares maximum demand with the reserved capacity you enter: utilisation in %, headroom and exceedance in kW and %, also for several measurements at once.
When you want to know how close your maxima get to the capacity — without a tariff calculation or a recommendation to change it.
An indicative hourly model of a day: PV self-consumption without and with a battery, and a check whether a battery covers one power peak.
When you want to understand what PV and a battery technically change for a given load profile — before any design work.
The calculations are for quick orientation and checks. They do not replace design documentation, manufacturer data or verification on the actual plant.
More tools will be added over time.
When the problem goes beyond a calculator, start with a technical analysis or send a brief.
