Description
Turn a basic WMI setup into an Aquamist-calibre system
Keep your setup. Replace the guesswork.
For over three decades, Aquamist has defined the standard in water/methanol injection.
Now, we’re introducing a new sensor designed to bring that same level of accuracy, reliability, and engineering quality to a wider range of systems.
Whether you’re running a standalone ECU or a non-Aquamist setup, this is your opportunity to upgrade the most critical part of your system — flow measurement.

Flow Sensor features
• Linear 0–5V analogue output
• 1/8 BSPP i/o ports
• Operating Range – Standard up to 1600cc and Hi-flow up to aprox 3000cc (Hi-flow selection in variations)
• Seamless integration with standalone ECUs
• Proven Aquamist sensor technology
• Engine bay temperature stability
• Adjustable sensitivity / scaling
• Compact inline design
Important Information
- This is a flow monitoring device only – No control or failsafe functions – Requires ECU calibration
-
Designed for use with Clean, filtered fluid (≤100 micron), High-purity methanol (>99%)
- For Hi-Flow – select in variations drop down
Electrical Specifications
- Input voltage: 12v to 14.5v
- Input current: 50mA
- Output: 0-5v ( 5mA)
- LED: >95% of full scale output
- pre-scales range adjustment span: up to approx. x2.5 (subject to future ugrade)
- The fully sealed sensor is not serviceable.
- Maximum environment temperature: 65C/150F
Mechanical Specifications
- I/O ports: 1/8BSPPF
- Standard flow sensor (C): Upto 1600 CC/M (linearity not guaranteed beyond 1600cc)
- High flow sensor (D): Upto 3200 CC/M (linearity not guaranteed beyond 3000cc)
- Bi-directional with 100 micron I/O SS disc filters
- Maximum Spanner/Wrench torque between mating components: <4Nm or 3 foot-pound)
- Avoid close to high temperature components
- Increase methanol concentrations to avoid freeze damages in cold winters
- Output readings will drop in cold temperatures as the fluid increase viscosity (increase methanol concentration)
Product Warranty coverage
- Covers manufacturer defects only
- Valid for 12 months from date of purchase
Exclusions
- Incorrect installation or wiring
- Incorrect calibration or ECU configuration
- Use outside intended application (water/methanol injections systems)
- Contaminated (hydrocarbon etc. or unfiltered fluid
- Use of unsuitable or low-purity methanol)
- Physical damage or modifications
- Exceeding specified maximum temperature
