Positive Displacement Flow Meter with Display
High-accuracy positive displacement oval gear flow meter with integrated digital display, designed for fuel measurement and industrial fluid monitoring. This meter provides real-time flow rate and totaliser readings directly on the built-in display, making it the ideal choice for diesel fuel consumption monitoring, batch control, chemical dosing, and fuel transfer systems where instant visual readout is required — no external display or PLC needed.

Frequently Asked Questions
What is a positive displacement flow meter with display used for?
A positive displacement flow meter with display is used to measure the volumetric flow of liquids like diesel fuel, oil, and chemicals with high accuracy. The built-in digital display shows real-time flow rate and cumulative total directly on the meter, enabling instant visual monitoring without requiring a separate PLC, controller, or external display.
Do I need a separate display or PLC to read this flow meter?
No. This flow meter comes with an integrated digital display that shows flow rate and totaliser readings directly on the unit. It is a standalone solution — no external display, PLC, or wiring is required. Simply install it inline and start reading.
What size flow meter do I need for my application?
Choose based on your flow rate: 2–100 LPH or 10–1000 LPH (1/4") for low-flow chemical dosing or lab use; 2–35 LPM (1/2") for small engines; 3–70 LPM (3/4") for generators; 6–160 LPM (1") for medium diesel transfer; 10–350 LPM (1-1/2") for bulk fuel; 15–580 LPM (2") for high-volume industrial. Each is available in BSPP or FNPT threads. Contact RAZQUIP for sizing assistance.
Is this meter suitable for high-pressure applications?
Yes. Depending on the size selected, this meter handles up to 128 bar working pressure and operates across a wide temperature range of -40°C to +120°C. The aluminium body with stainless steel shafts and Viton seals provides durability in demanding industrial environments.
