商品説明

This flowmeter is precise and sophisticated. It must be accurately calibrated for application conditions. If in doubt, consult OMEGA’s Flow Department.

OMEGA™ FMA-8500 Series high pressure mass flowmeters feature a superior ±0.25% repeatability for accurate measurement and control of gas flow. The flow sensor produces a 0 to 5 Vdc output signal linear to the mass flow rate for use in recording, indicating, or control purposes.

(*) You must specify gas and inlet/outlet pressure when ordering.

1) Select the core part number from the range code table above.
2) Add the gas and inlet/output pressure information after the core p/n, eg.: FMA-8501-Nitrogen,20/0 psig (This is a FMA-8501 0 to 20 SCCM, flowmeter for nitrogen, with an inlet pressure of 20 psi, and outlet pressure of 0 psi)
3) Enter the Constructed part number in the "Order Specific Models Here" table below!
4) You will then add the p/n to your cart and check out with a non-std p/n.
5)We will confirm by email and/or telecon price and availability after the order is placed.

注: Comes complete with mating connector and operator's manual.

Calibrations done at ambient temperature only 20°C(70°F).

* Please specify gas and inlet/outlet pressure. When ordering, replace the "*" in the suffix with the gas and inlet/outlet pressure information.

For calibrations between 201 and 900 psig; add $600 to price.

For calibrations between 901 and 4500 psig; consult Flow Engineering for pricing.

For NIST certificate, add suffix "-NIST" to the model number; consult Flow Engineering for pricing. NIST certificate does not include points.

All models are custom, consult specification page for complete description and list of available models.
