Compact Flowmate & Super Micro
Request a Quote
The Flowmate and Super Micro Flowmate from OVAL are compact positive displacement flowmeters designed for precise small and ultra-small flow measurement.
Equipped with a built-in pulse transmitter, they provide robust, low-cost performance and are ideal for monitoring fuel consumption in burners, heaters, and fuel cells, as well as chemical and food additive dosing.
With accuracy of ±1.0% RD and measurement capability down to 1.5 mL/min (38 model), they support a wide range of applications in research, energy, and industrial processes.
Features
- Compact flow meter with built-in pulse generator
- Simple, robust, and cost-effective design
- Suitable for centralized display and monitoring as a fuel meter for burners/heaters or as a totalizer for small flow rates
- Can be combined with valves or pumps for compact proportional injection and flow control of chemicals or food additives
- Ideal for ultra-low flow measurement, such as in fuel cell applications (Model 38 can measure from as low as 1.5 mL/min)
- High accuracy: ±1.0% RD (Models 40, 41, 45)
Applicable fluid
- Water
- Gasoline
- Kerosene
- Diesel Fuel
- Heavy Oil
- Others
