Pump Head from Gauge Readings
Actual developed head from suction & discharge gauges, including gauge elevation offset.
Forgetting the gauge-height correction is the classic field-test error. Read both gauges at the same instant โ system transients lie.
Formula
Pump Head from Gauge Readings is a free pump head measurement for pump engineers, plumbers and plant designers โ instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Pump Head from Gauge Readings
Actual developed head from suction & discharge gauges, including gauge elevation offset. The calculation implements H = (P_d โ P_s)/ฯg + ฮz_gauges (+ velocity-head difference if bores differ) (ANSI/HI 14.6 โ field acceptance tests). Forgetting the gauge-height correction is the classic field-test error. Read both gauges at the same instant โ system transients lie.

Frequently asked questions
What formula does the Pump Head from Gauge Readings use?+
It computes H = (P_d โ P_s)/ฯg + ฮz_gauges (+ velocity-head difference if bores differ), per ANSI/HI 14.6 โ field acceptance tests. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Forgetting the gauge-height correction is the classic field-test error. Read both gauges at the same instant โ system transients lie.
Can I use this for pump selection?+
Use it to establish the duty (flow, head, NPSH, power) and then pick a pump whose curve passes through that point near best efficiency. The tool gives you the engineering numbers a supplier will ask for.
Is the Pump Head from Gauge Readings free to use?+
Yes โ completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
