About this app

On site, have you ever wondered, “What flow rate and head is this pump running at right now?” or “How much energy would an inverter save?”
This field diagnostic simulator answers those questions on the spot.
■ Estimate the operating point from the pump's performance curve, on the spot
Just register the pump model (rated flow, rated head, rated shaft power, etc.) to generate the performance curve (H-Q curve), efficiency curve, shaft power curve, and current curve. Simply tap on the graph to instantly see the estimated flow rate, head, shaft power, efficiency, and current at that operating point, along with the deviation rate from the rated point.
■ Improve accuracy with field-measured data
In addition to the rated point from the nameplate, you can add flow rate, total head, and other data measured on site. The curve is then automatically adjusted to pass through the measured points for a more realistic fit. If you have a pump performance test report (a detailed list of measurement points), you can register it as-is to reproduce a highly accurate curve.
■ Inverter simulation (3 patterns)
• Fixed resistance curve: Estimates the operating point when the frequency is changed while keeping the current piping resistance
• Fixed flow rate: Assumes a switch from valve-throttling operation to an inverter, and estimates whether the same flow rate can be maintained
• Affinity law estimate: A simple estimate based on the affinity laws (Q∝N, H∝N², P∝N³) alone, without considering system conditions
Just move the frequency slider and watch each value update in real time. If a condition can no longer be maintained beyond the range of the performance curve, a warning is shown at a glance.
■ Manage multiple sites and units together
Manage a list of pumps by site name, installation location, and unit name. When registering a spare unit of the same model, you only need to select the model — there's no need to re-enter the nameplate information.
■ Recommended for
• Facility maintenance and energy-saving diagnostics staff at factories and plants
• Anyone considering pump replacement or inverter installation
• Design and construction staff who want a quick, simplified performance check on site
■ Before you use this app
The values shown in this app are approximate, calculated using general-purpose fitted curves based on the registered rated point and measured data. They do not guarantee actual performance. For important decisions, always check the manufacturer's official performance curves and measured data.
■ Use with peace of mind
No account registration is required. The pump information you enter is processed only on your device and is never sent to an external server.
