Gas Meter RMG
Gas Meter RMG VOLUMETER TRZ 03-K Description : LF-Pulse transmitter (in the meter head) Standard : reed contact Alternatively : inductive pulse transmitter Option : up to 3 LF pulse transmitters possible HF-pulse transmitter(Option) • In the meter head: Inductive pulse transmitter (HF 1), pulse frequency at Qmax approx. 100 Hz. • In the meter case: Inductive pulse transmitter for scanning - the blades of the turbine wheel (HF 3, from DN 80) - the cams of the reference wheel (HF 2, from DN 100) All inductive pulse transmitters provide volume pulses incompliance with NAMUR. Meter head (type “F”) • Protection class IP 65 • Universally readable • Totalizer unit and HF1 pulse transmitter are easily replaceable on site. Measuring range: up to 1:16 Nominal size: DN 50 through DN 600 Special designs with larger nominal sizes up to DN 1000 are possible. Pressure rating: PN 10 through PN 100, ANSI 150 through ANSI 600 Special designs with a higher pressure rating are possible. Operating temperature range: Standard design: -10°C to +50°C Special designs for higher and/or lower temperatures are possible. Explosion protection The pulse transmitters are intrinsically safe; their type of protection is EEx ib IIC T6. Therefore, the TRZ 03-K can be operated in Zone 1. Long service life pr-connection To connect the pressure transmitter of a PTZ corrector. Manufacturer‘s test certificate In compliance with EN 10204/2.3, for strength and leak testing.
