Jual Gas Meter RMG

Definisi Gas Meter

Alat untuk mengukur kuantitas atau laju aliran gas. Jenis meter gas (berdasarkan prinsip operasi) termasuk perpindahan, kecepatan, kepala, termal, akustik, dan pelacak. Contoh dari prinsip perpindahan adalah meteran gas bellow-dan-diafragma (ditunjukkan dalam diagram).

Tubine gas meter / flow meter gas turbine

Selama pengukuran, molekul gas cenderung berjalan melalui meteran secara terus menerus, yang menghasilkan denyut selama kalibrasi. Peredam suara dapat digunakan untuk menghindari kesalahan pengukuran yang signifikan.Sistem roda gigi, roda turbin, bagian ekstrusi, dan unit rumah tertutup adalah komponen utama meter turbin.Saat gas mengalir, roda turbin mulai berputar. Putaran roda turbin sebanding dengan kecepatan aliran. Oleh karena itu, volume gas dapat dihitung sehubungan dengan putaran roda.

Deskripsi

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.

Material
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

Accuracy
Error limits (standard):
±2% for Qmin to 0.2 Qmax (DN 50, DN 80: ±3%)
±1% for 0.2 Qmax to Qmax (DN 50: ±1.5%)
These limits apply in the event of a steady, swirl-free fl ow.
Higher accuracy available on special request.

Repeatability: ±0.1%
All gas meters are tested in the factory with air under
atmospheric pressure.

Approvals
The gas meters substantially comply with PTB and
EC/EEC regulations (G120 3B of the EC dated September 6, 1971).
The TRZ 03-K Volumeter has been examined according
to the pressure equipment directive 97/23/EC by DVGW
and is registered under the product ident number
CE-0085BN0292.
The TRZ 03-K Volumeter meets the OIML guideline
IR-32/89, Annex A.
