TME 400 (VM / VC / VMF / VCF) — electronic turbine gas meters with built-in volume corrector, DN 25–400
TME 400 are electronic turbine gas meters DN 25–400 with built-in volume correction in some versions. The VM and VC versions are for process metering, VMF and VCF for custody transfer metering (MID). The meters are intrinsically safe, approved for zones 1 and 2, and have an RS485 Modbus output.

Description
TME 400 (Turbine Meter Electronic) is a family of electronic turbine gas meters. Compared with classic mechanical turbine meters, they show the current flow, archive data and parameters, have a variety of interfaces and, in some versions, built-in volume correction. The measuring section is based on the proven TRZ 03-K series, and the dimensions and metrological characteristics are identical.
Unlike a mechanical meter, the TME 400 has a magnetic disc on the turbine wheel shaft that is scanned by a Wiegand sensor. Each revolution produces one electrical pulse proportional to volume, and the electronic head processes the pulses and displays and stores the readings. This makes several totalizers possible (main, start-up or resettable, low-flow cut-off by an external signal), indication of instantaneous and maximum flow, and data transmission over pulse, analog and digital channels.
TME 400-VM is a volume meter for process (non-custody) metering. TME 400-VC additionally contains a full PTZ corrector with digital pressure and temperature sensors and calculates the standard volume. The compressibility factor is taken according to SGERG-88, AGA8 Gross M1 and M2 or AGA NX19, so no external corrector is needed. TME 400-VMF and TME 400-VCF are intended for custody transfer metering (MID) and are tested by DIN-DVGW. They have two configurable pulse inputs, a Pt1000 input, a digital pressure input, an HF output with a pulse width of 1 ms and an LF output of 20, 125 or 250 ms, and an optional remote display at a distance of up to 10 m.
The family sizes range from DN 25 (flow 2.5–25 m³/h) to DN 400 (650–10,000 m³/h), with DN 500 and 600 on request. Housings are made of steel or ductile iron, welded steel, aluminium or stainless steel, with pressure classes from PN 10/16 to ANSI 600 depending on size. The outputs are HF and LF pulses, an alarm output, 4–20 mA current (optional) and an RS485 Modbus interface. Power comes from a lithium battery for more than 6 years or from an external supply with a backup battery. The terminals of the pressure and temperature inputs are sealed separately, and the battery is replaced without opening the housing. The meters are intrinsically safe and approved for zones 1 and 2, and parameterization is done with the manufacturer's TME configuration software. They are used at metering points of industrial plants, boiler houses, gas control points and gas distribution stations, and the VMF and VCF versions in custody transfer metering at consumers.

Questions and answers
What sizes and flow ranges does TME 400 have?
From DN 25 with a flow of 2.5–25 m³/h to DN 400 with a flow of 650–10,000 m³/h. DN 500 and 600 are made on request.
How do the VM and VC versions differ from VMF and VCF?
VM and VC are intended for process metering, and VC additionally has a built-in PTZ corrector. VMF and VCF are intended for custody transfer metering (MID) and are tested by DIN-DVGW.
Can the meter be installed in hazardous areas?
Yes, the meters are intrinsically safe and approved for zones 1 and 2. Power comes from a lithium battery for more than 6 years or from an external supply with a backup battery.
