The VA 500 is a thermal mass flow meter for compressed air and gases. It reads consumption directly as mass flow or standard volume flow. The FA 510/515 is a dew point sensor for compressed air and gases, used after refrigeration, adsorption and membrane dryers. The manufacturer’s program also covers leak detection, energy management and compressed air quality measurement, which we can quote on request.
CS Instruments products we list
Ordering CS Instruments devices: what we need
For a CS Instruments flow meter, send the pipe inner diameter, line pressure, gas type and expected flow. For a dew point sensor, state the dryer type and the dew point range you need to measure. In both cases tell us the output you want to wire to and send the existing order code if the item is a replacement. We serve buyers across the GCC.

FAQ
Questions about CS Instruments
Common questions about CS Instruments equipment, part numbers and supply to Oman and the GCC.
01What does the CS Instruments VA 500 measure?
The VA 500 is a thermal mass flow meter for compressed air and gases. It gives flow and consumption as mass flow or standard volume flow without separate pressure and temperature compensation. The sensor is set up for a pipe diameter and gas type, so both must be stated when ordering.
02What is the difference between FA 510 and FA 515?
Both are CS Instruments dew point sensors for compressed air and gases, listed together by the manufacturer. Two measuring ranges are offered: -20 to 50 °Ctd for use after refrigeration dryers and -80 to 20 °Ctd for adsorption dryers. Send the dryer type and the signal you need, and we confirm the version and order code.
03Which gases can CS Instruments sensors handle?
For its dew point sensors the manufacturer lists air, nitrogen, oxygen, argon, carbon dioxide, hydrogen, methane and natural gas or biogas, with other mixtures on request. The VA 500 flow meter is described for compressed air and gases. Each sensor is set up for its gas, so state the exact gas or mixture when you ask for a quotation.
04Who founded CS Instruments?
CS Instruments was founded in Germany in 2002 by Christian Schuldt and Wolfgang Blessing. It is based in Harrislee, near Flensburg, with a second site in Tannheim, and specialises in measurement instruments for compressed air and gases.
05Is Seven Star LLC a distributor of CS Instruments?
No. Seven Star LLC is an independent industrial supplier based in Muscat. We source CS Instruments devices through commercial channels, check the model or order code against the manufacturer's documentation before quoting, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order on request.
