GESPASA Electronic Gear Flow Meters – 1", 1-1/2" & 2"
Description
GESPASA Electronic Gear Flow Meters are designed for accurate measurement and totalisation of diesel and lubricant flow. Available in 1", 1-1/2" and 2" connection sizes, the range combines an aluminium measuring body, precision oval gears and a clear digital LCD display.
Battery-powered operation eliminates the need for a permanent power supply, making these meters well suited to workshops, farms, fuel systems and industrial fluid-transfer installations.

GESPASA Diesel & Lubricant Electronic Gear Flow Meters
These digital gear meters measure and totalise flow through the meter body using precision-machined oval gears. The electronic display provides a clear readout of both the current dispensed volume and accumulated total flow.
Electronic Flow Meter Features

Available Models
The range includes three models to suit different flow rates and connection sizes:
- MGE-250: 1" BSP female
- MGE-250-15: 1-1/2" flanged
- MGE-400: 2" BSP female
Flow Ranges
Flow capability varies depending on both the model and fluid viscosity.
| Model | Diesel Flow Range | Lubricant Flow Range |
|---|---|---|
| MGE-250 | 10–250L/min | 10–150L/min |
| MGE-250-15 | 10–250L/min | 10–150L/min |
| MGE-400 | 15–400L/min | 15–300L/min |
Digital Display & Totaliser
The LCD display provides two useful functions:
- DISPLAY: shows the dispensed litres for the current transfer
- TOTAL: shows accumulated totalised flow up to 99,999
This makes the meter suitable for both individual dispensing measurements and longer-term volume tracking.
Battery Powered Operation
The meters use a long-life button battery with a stated life of up to 4 years, depending on usage and operating conditions.
A low-battery warning helps indicate when the battery is approaching replacement.
Compatible Fluids
The supplied compatibility information lists:
- Diesel
- Lubricants
- Fluids with viscosity from 2–2000 cSt
- Oils up to SAE 140 density
For fluids outside these specifications, confirm chemical and viscosity compatibility before use.

Installation Considerations
Select the correct model according to connection size, expected flow range and fluid viscosity.
For best measurement performance, ensure the meter is installed within its stated pressure, temperature and flow limits and that the fluid is free from debris that could affect the internal measuring gears.
