Category · Meters & flow meters for AdBlue® / urea AUS 32

AdBlue® meters for accurate quantity recording & consumption control

Electronic flow meters and pulse counters for urea solution AUS 32 – as a compact display unit, as a retrofit kit for HORNET systems or as a pulse counter for external display and control. From Tecalemit and PIUSI, for 5 to 120 l/min.

✅ 5 – 120 l/min measuring range ✅ Display meter · pulse counter ✅ For AdBlue®, diesel & water ✅ Tecalemit FMT 3 · PIUSI K24 & TURBINOX

Electronic display meters

The Tecalemit FMT 3 III (€168) with a 6-digit LC display, a 2-line LED indicator and a wide measuring range of 5–120 l/min for diesel, AdBlue®, heating oil and water. The PIUSI K24 with a universal 1" connection (€204.50) is designed specifically for AdBlue® – direct reading of the delivered quantity.

Retrofit kit for the HORNET W85H

The Tecalemit FMT 3 III as a meter retrofit kit specifically for HORNET W85H INOX pump systems (€190) – a 1" thread, a measuring accuracy of ±1% after calibration, max. 10 bar. Retrofittable to existing HORNET systems without replacing the pump.

Pulse counter without a display

The PIUSI TURBINOX (€262) and TURBINOX 90° (€338) made of stainless steel – a pulse counter without its own display that transmits an output signal to an external counter, controller or fuel management system. 10–40 l/min, max. 20 bar, for installation in stationary dispensing systems and fleet management systems.

Which meter type when?

Display meters (FMT 3, K24) are suitable for simple, directly readable quantity recording without further infrastructure. Pulse counters (TURBINOX) are needed when the measurement data is to be passed on to a higher-level controller – e.g. a fuel management system, fleet management or a fuel-data collection system.

Which AdBlue® meter suits which application?

🔢

Simple quantity display

For direct reading of the dispensed quantity without a further system: Tecalemit FMT 3 III (€168) – a compact display, 2-line illuminated, for diesel, AdBlue® and other media. A low-cost entry into consumption recording without additional hardware.

🔧

Retrofitting the HORNET W85H

For operations with an existing TECALEMIT HORNET W85H INOX pump system without a flow meter: FMT 3 III retrofit kit HORNET (€190) – a matching 1" threaded connection, ±1% measuring accuracy after calibration, max. 10 bar. Direct mounting without a pump conversion.

🚛

Fleet with its own fuel management system

For systems with an existing fuel management system (TECALEMIT HDA eco, PIUSI MCBOX) or fleet management software: PIUSI TURBINOX pulse counter (€262) – passes a pulse signal on to an external controller, no display of its own. A stainless-steel housing for long continuous operation.

📐

Space-saving installation – 90° connection

For cramped installation situations in compact systems or with difficult hose routing: PIUSI TURBINOX 90° (€338) – identical specification to the straight TURBINOX, but with a right-angled connection for more flexibility during installation.

💧

Several media – one meter

The Tecalemit FMT 3 III is approved for diesel, heating oil, AdBlue®, RME, radiator antifreeze and water – ideal for operations that measure several liquids and want to keep only one device. The PIUSI K24 is optimised specifically for AdBlue®.

⚙️

Meter integrated in the dispenser

Many dispensers and pump systems already have integrated meters – check before purchasing whether your system contains a meter. The HORNET W85H INOX with FMT 3 (€846) and the PIUSI DELPHIN PRO have integrated meters. A separate meter is only needed for systems without a meter or for retrofitting.

Frequently asked questions about AdBlue® meters

A display meter (FMT 3 III, PIUSI K24) has its own LC or LED display on which the delivered quantity can be read directly – no external display or controller needed. A pulse counter (PIUSI TURBINOX) outputs an electrical pulse per litre delivered (or fraction thereof), which is processed by an external unit – e.g. a fuel management system, fleet management system or PLC controller. Pulse counters are suitable for integrated systems; display meters for simple, self-contained solutions.
Yes – the Tecalemit FMT 3 III is approved for several media: diesel, heating oil EL/L, AdBlue®, RME (biodiesel), radiator antifreeze (concentrate) and water. It is thus one of the most versatile meters in the range and is suitable for combined refuelling systems in which a single device is to record several liquids. The PIUSI K24, on the other hand, is optimised specifically for AdBlue®.
The measuring accuracy varies depending on the model and the operating conditions. The FMT 3 III retrofit kit achieves an accuracy of ±1% after calibration. Turbine counters such as the PIUSI TURBINOX also work very precisely within the optimal flow range (10–40 l/min). Important: measuring accuracy depends on the flow rate, temperature and correct installation (a straight inlet section). For calibratable measurements (billing to third parties), special calibrated meters are required – the models offered here are designed for internal operational consumption recording.
AdBlue® corrodes many metals (copper, brass, zinc) and attacks certain plastics. Standard flow meters for diesel or water are often made of these materials and are therefore not suitable for AdBlue®. AdBlue® meters use exclusively corrosion-resistant materials: PVDF, PP, stainless steel and chemical-resistant seals (EPDM, PTFE). In addition, the electronics must be protected against the slightly conductive urea solution.
The FMT 3 III retrofit kit is configured specifically for mounting on the TECALEMIT HORNET W85H INOX and is fitted with the matching 1" threaded connection (internal/external). It can in principle also be used on other systems with a 1" connection, provided the pressure range (max. 10 bar) and flow (5–120 l/min) are suitable. The regular FMT 3 III (€168) is the more universal model without a system-specific adaptation – both are based on the same measuring unit.
The PIUSI TURBINOX is a turbine-wheel flow meter with a pulse output: a small turbine turns with the flow, and an electrical pulse is output per rotation (or fraction thereof). An external counter, fuel management system or PLC controller counts these pulses and calculates the delivered quantity from them. The pulse factor (pulses per litre) must be set correctly in the external system. The TURBINOX housing made of stainless steel allows a high operating pressure up to 20 bar – suitable for high-pressure applications in stationary systems.
