A recognized leader in natural gas measurement and control, RMG has enhanced its product portfolio with the EC 600—a certified and best-in-class electronic volume corrector. The EC 600 offers a low total cost-of-ownership and meets gas volume conversion requirements at exit points throughout the natural gas industry. It is a proven and precise gas measurement solution.
Proven Performance. Robust Functionality.
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 in compliance with NAMUR.
Meter head (type “F”)
-Protection class IP 65
-Totalizer unit and HF1 pulse transmitter are easily replaceable on site.
Measuring range: up to 1:30
With high-pressure testing, an expansion up to 1:50 is possible.
DN 50 through DN 600
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.
Thermowell inside the meter case (option)
To accommodate a resistance thermometer.
The pulse transmitters are intrinsically safe; their type of protection is EEx ib IIC T6. Therefore, the TRZ 03 can be operated in Zone 1.
To connect the pressure transmitter of a PTZ corrector.
Rotor: Delrin for DN 50 to DN 200 and PN 10 / PN 16.
Aluminium alloy for all other diameters and pressure ratings and for meters with HF sensors.
Aluminium rotors instead of delrin rotors on special request.
Error limits (standard):
±1.0% for Qmin to 0.2 Qmax ±0.5% for 0.2 Qmax to Qmax
Higher accuracy available on special request.
The meter head is ﬁ tted with a reed contact as LF pulse transmitter as standard feature. But optionally, another two sensors can be ﬁ tted, e.g. another LF pulse transmit-ter (inductive sensor with output pulses complying with NAMUR or reed contact) and an HF1 pulse transmitter (NAMUR).
All turbine meters are ﬁ tted with a lubricator (DN 50 through DN 150: permanent lubrication, from PN 25/ANSI 300 pushbutton pump; DN 200: pushbutton pump; from DN 250: lever pump). Lubrication must be performed in compliance with the operating instructions (see also the lubrication instruc-tion plate of the gas meter). If clean gas is used, lubri-cation is to be performed at 3-month intervals, whereas lubrication must be performed more frequently if dust- and/or condensate-laden gas is used.
