Hydraulic & Pneumatic Flow and Pressure Measurement Systems

Curtis Assemble & Test Ltd design and manufacture bespoke flow and pressure test machines for hydraulic and pneumatic systems. These machines are used to verify valve performance, flow rates, differential pressure, and Kv values. With stainless steel construction, integrated drip trays, and interlocked guarding, our systems provide accurate, reliable, and safe performance for demanding applications.

System Capabilities

Our machines incorporate a range of self-priming and variable speed pumps, ensuring flexibility across different pipe sizes and expected flow ranges. Control systems allow smooth switching between pumps during testing for consistent, repeatable results.

Modes of Operation

Manual Operation:


✔️ On/off and pump speed settings via integrated control panel
✔️ Flow meter selection using manifold isolation valves (auto option available)
✔️ Differential pressure display via manometers or pressure transducers
✔️ Isolation valves allowing up to 100% spill-off for low flow testing
✔️ 0–10V outputs for additional component control (e.g. actuators)
✔️ Manual balancing valves for fine tuning

Automated Operation:


✔️ PC-controlled pump speed and spill-off
✔️ Live readout of flow, inlet pressure, outlet pressure, and differential pressure
✔️ Automated programs to servo to flow, pressure, or locked conditions
✔️ Automated pump control for repeatable testing to defined parameters
