Dear Supplier,

We are developing a prototype for a Compressed Natural Gas (CNG) vehicle dispenser. Our system operates with an inlet CNG pressure ranging from 2900 psi to 3500 psi (approx. 200-250 bar).

If our prototype is successful and approved, we plan to manufacture an initial batch of 250 dispenser units.

Therefore, we are currently looking for suppliers for components. We would like to request a quotation for:

Pricing for sample quantities needed to build our initial prototype.
Bulk pricing for supplying these components for our planned production of 250 dispensers.

The components should have 1/2" NPT Female connections or compatible. Piping will be 1/2" NPS.

Coriolis Mass Flow Meter (Quantity for Prototype: 2)

Function: Accurately measure dispensed CNG mass.
Wetted Parts Material: Stainless Steel 316/316L.
MAWP: 250.
Temperature Range: -40°C to +85°C (or per manufacturer spec).
Connections: 1/2" NPT Female (Please confirm availability, adapters acceptable if needed).
Accuracy: High precision required (e.g., ±0.5% of reading or better).
Output Signal: Specify required (e.g., Pulse, 4-20mA, Modbus/HART).
Hazardous Area Certification: Mandatory for transmitter/electronics. Class I, Division 1, Groups C & D or ATEX/IECEx Zone 1 equivalent. Metrology certifications (OIML R139, NTEP) are a plus.
