Case studies
"We design and manufacture a wide range of liquid level, pressure, temperature control and monitoring equipment for worldwide customers."
Application: L70 coolant check system for bus manufacturer
Problem
Engine coolant level is not always checked, or available to be checked, before the vehicle enters service that day. If the coolant is low then extensive engine damage may be caused. The cost implications arising include engine repair or replacement, engineer’s time, towing costs and consequential loss of revenue whilst the vehicle is out of service.
Additional constraints
- Visible indication of liquid level must be viewable at all lighting levels .
- Control panel to be fitted as either OE or as a retrofit.
Solution
L70 coolant level check system
Benefits
- Comprises two parts - a coolant level switch and a control panel
- Simple operation using high quality capacitance level switch
- Control panel has two LEDs - green for OK coolant level red for low level
- Easy to fit and the remote panel can be located at the driver's convenience

Application: G/LL146 for microlight aircraft
Problem
Microlights generally have no fuel gauge and the fuel tank is located immediately behind the pilot's seat. To check the fuel level the pilot uses a hand held mirror to view the tank.
Additional constraints
- Microlight aircraft are categorized by the CAA as Ultralight Aircraft so any additional items to be fitted also need to be of minimal weight.
- These aircraft have a very light duty electrical system.
Solution
G/LL46 hydrostatic gauging system
Benefits
- Its weight of 80g incurs little weight penalty
- There is no electrical supply or wiring
- The capillary tubing is fed through the tubular structure of the aircraft thereby protecting it
- Being all plastic the gauge is unaffected by corrosion

Application: Bund Monitor for fuel storage tanks
Problem
Industrial and domestic fuel tanks above a certain size are required to have a bund, or secondary containment device, to prevent any leaks from the tanks entering the environment and particularly any water course. The bund must have a capacity of 110% of the tank.
Additional constraint
- Weekly testing of the system is recommended.
Solution
BM series Bund Monitor
Benefits
- Established and proven technologies are used
- Very easily installed either as original equipment or retrofit
- Low cost
