Mobile hydraulic calculator built for on-site engineering use
FluidsMaster Hydraulic Calc, from Rohhman Fluid Systems, is a portable calculation tool for hydraulic system diagnostics and sizing. The app performs specialized computations for cylinders, pumps, motors, piping, accumulators and unit conversion directly on Android devices. It bundles unit switching, fluid property lookups, and multiple formula sets into a single mobile interface. Designed for hydraulic designers, maintenance technicians, and engineering students who need fast, field-ready numeric checks and reference data.
Can FluidsMaster deliver the core hydraulic results engineers need?
FluidsMaster targets the numeric tasks common in fluid power work: determining cylinder force and speed, pump displacement and motor torque, and pipe pressure drop and velocity. The app presents calculation modules that map directly to engineering outputs, so users can generate the basic parameters required during component selection and verification without switching tools.
How does the tool fit into on-site troubleshooting and audits?
The app focuses on quick entry and rapid results, with a field-ready layout optimised for mobile use. Key on-site routines include:
cylinder extension and retraction sizing
pump and motor power checks
pipe flow and pressure-drop estimates
These modules condense multiple hydraulic formulas into one place, speeding numeric checks during inspections and commissioning.
Is the interface and unit handling suitable for cross-region projects?
FluidsMaster supports Metric and Imperial unit systems and includes built-in unit conversion and a fluid property reference to adjust calculations for fluid characteristics. The app runs on Android and stores computations locally on the device, so unit toggling and property lookups occur without network access, which helps when projects span regions that use different measurement systems.
What are its limits for team workflows and formal design use?
The tool performs calculations offline and is oriented toward single-device use, which matches individual field checks and student work. User reception notes it as a straightforward technical reference, but formal design workflows that require shared project files, centralized revision control, or final approval processes are outside the app's stated remit; it serves best as a mobile verification and estimation aid.
Practical mobile companion for field calculations, not a replacement for formal design packages
FluidsMaster is a practical option for hydraulic engineers, technicians, and students who need immediate, on-site numerical checks and fluid property lookups. Its offline operation and unit conversion make it reliable for rapid verification, but it is not intended to replace formal engineering design tools during final approvals. Use it as a mobile reference during commissioning, maintenance, and preliminary sizing tasks.
Pros
Dedicated modules for cylinders, pumps, motors, and piping calculations
Dual Metric and Imperial unit support with built-in converters
Offline operation performs calculations locally on Android devices
Cons
Intended as a reference, not a substitute for formal design approvals
Android-only app limits use on non-Android devices
Oriented toward single-device field work rather than team file sharing
