Premier Control Technologies Fluid Solutions
The UK and Irish automotive sector spans ICE, hybrid and EV platforms, where repeatable test results, robust plant reliability, and traceable quality controls are non negotiable. From engine dyno cells and fuel return loops to battery electrolyte filling and paint shop utilities, PCT supplies measurement and control technologies that are proven on benches, rigs and production lines.
Our portfolio covers Coriolis mass flow for fuels, back pressure and pressure regulation for steady utilities, rugged visual indication for coolant/lube branches, and precision dosing for additive, sealant and solvent handling—backed by UK support and service. We integrate quickly with existing PLC/SCADA environments and can advise on materials, approvals (e.g., ATEX/IECEx where applicable), and lifecycle considerations to reduce risk and downtime.
Engine dyno programs rely on accurate, fast responding mass based fuel measurement across warm up, step transients and coast downs. Volumetric meters can drift with density changes; direct mass and density measurement simplifies corrections and improves correlation across fuels and temperatures. Compact, vibration tolerant sensors help when space is tight and test cells are busy. High pressure capability is valuable for modern high pressure rails and return circuits. Built in temperature output supports energy accounting and viscosity studies. The result is tighter BSFC calculations, cleaner step responses and less re run risk.
Stable back pressure in fuel return loops is essential to keep injectors within their operating envelope and maintain repeatable rail conditions. Return flows can swing rapidly during step tests and tip outs, so the regulator must remain stable through large turndown without hysteresis. Mixed phase tolerance helps when cavitation or vapour pockets appear. Cleanliness and material options matter for compatibility with different fuel chemistries. Electronic piloting enables remote, programmable set points for automated profiles.
Coolant circuits protect powertrain and e motor components and often include branch monitoring for pumps, heat exchangers and inverter cooling plates. Many sites need local indication plus a simple way to add alarms or 4–20mA to a PLC. In rugged bays, stainless steel meters with elevated temperature/pressure ratings reduce maintenance. When technicians need a glanceable check plus a signal, variable area instruments with stainless internals are the practical choice.
Transmission, axle and bearing rigs demand reliable lube flow confirmation to protect expensive test articles. Fluids can vary in viscosity with temperature; mass based measurement sidesteps density corrections. Compact sensors help where manifold space is tight, and high temperature capability is useful during heat soak testing. Diagnostics and density data can inform condition monitoring and aid root cause analysis after anomalies.
Battery module production requires repeatable micro to millilitre level dosing of electrolytes and additives, with strong chemical compatibility. Valveless architectures reduce clog/leak points and maintain accuracy over many cycles, avoiding downtime and rework. Swappable heads and material options help match chemistries across pilot and scale up. Clean, compact modules integrate neatly with PLCs for recipe control and feedback.
DEF handling on engine and after treatment rigs benefits from sanitary fluid paths, easy cleaning and flexible flow ranges. Peristaltic technology confines fluid to the tubing, reducing contamination risks and simplifying maintenance. Multi head drives support parallel channels or recirculation without complex manifolds, while RS 485 or analogue inputs enable recipe control.
Adhesives/sealants need precise, repeatable shots to avoid rework and cosmetic defects. Positive displacement dosing that is insensitive to back pressure swings improves consistency, and chemically resistant wetted parts handle challenging formulations. Modular heads let you set volumes mechanically and maintain accuracy over long duty cycles.
Paint shop flushing and solvent dosing benefit from closed loop pressure control to stabilise flow through guns, manifolds and return lines. Fast pressure steps reduce solvent waste and shorten changeovers. Electronic pressure controllers integrate easily with PLCs for automated sequences and alarms, improving repeatability shift to shift.
Sampling systems around catalytic converters and DPF after treatment require stable flow or pressure control and often operate in classified areas or harsh locations. Intrinsically safe instrumentation simplifies compliance and allows remote verification and data logging. Low leakage valves and robust enclosures are important for uptime and traceability.
Purge and vent services (e.g., nitrogen purge of test vessels, enclosures, or exhaust headers) demand reliable pressure regulation with low hysteresis and good set point stability. Clean materials of construction support analyzer and lab services, while a push and lock mechanism prevents drift from vibration.
Leak testing appears across the vehicle lifecycle—from component benches to final assembly checks. The method often needs precise control/hold of pressure and high resolution measurement of tiny flow/pressure changes. Minimising dead volume and enabling quick, portable verification reduces cycle time and rework. Battery powered tools accelerate audits around lines and bays.
Thermal/environmental chambers typically rely on stable pressure for steam, thermal fluids or conditioned gases feeding coils and atomisers. Self operated regulators lower complexity and provide quiet, fast response while maintaining downstream set points. Sliding gate internals reduce turbulence, wear and noise—valuable in lab/test areas.
