Name: RCM Compressed Air Survey Kit
Brand: RCM Industries
Availability: InStock

Question 1

What is the Air Survey Kit used for?

Accepted Answer

The Air Survey Kit is a portable tool for auditing compressed air systems. It is used to verify compressor output, measure air consumption at individual machines or departments, identify leaks and waste, and compare air consumption of similar devices. Studies show that up to 30% of compressed air at many facilities is wasted through leaks and inefficiency.

Question 2

How does the kit work?

Accepted Answer

The kit uses a Series 7000 RCM Flo-Gage with a special aluminum body and quick-change pipe adapters. You install the kit temporarily in the compressed air line using the included adapters, select the appropriate orifice for your expected flow range, and read the flow directly from the 3.5″ analog dial. A pressure gauge (SK1 models) allows you to apply pressure correction factors for accurate SCFM readings.

Question 3

What pipe sizes does the kit support?

Accepted Answer

The kit is available for 1″, 2″, and 3″ pipe sizes. Each kit includes 5 customer-selected flow range orifices, quick-change aluminum pipe adapters, and an aluminum inlet manifold with a pressure tap. The 1″ kit handles up to 400 SCFM, the 2″ up to 2,000 SCFM, and the 3″ up to 4,000 SCFM.

Question 4

What is the difference between SK1 and SK2 models?

Accepted Answer

SK1 models include a 4″ pressure gauge (0–160 psig, ±1% F.S.) for reading line pressure at the meter. SK2 models do not include the pressure gauge. The pressure gauge is useful for applying pressure correction factors when your system pressure differs from the calibrated pressure of 100 psig.

Question 5

What pressure and temperature is the kit calibrated for?

Accepted Answer

The Air Survey Kit is calibrated at 100 psig and 80°F. If your system operates at a different pressure or temperature, correction factors must be applied to convert the reading to actual SCFM. Correction factor tables are included in the instruction manual supplied with the kit.

Question 6

What accuracy can I expect?

Accepted Answer

The kit provides ±3% of full scale accuracy — the same as the standard Flo-Gage. For best accuracy, select the orifice that places your expected flow in the upper half of the scale (60–90% of full scale). The minimum readable flow is approximately 15% of full scale.

Question 7

How do I select the right orifice for my flow range?

Accepted Answer

Each kit includes 5 orifices covering different flow ranges. Select the orifice whose full-scale range is closest to — but greater than — your expected maximum flow. The kit includes an orifice change tool and instruction manual with flow range data for each orifice.

Question 8

How do I find compressed air leaks with the kit?

Accepted Answer

Install the kit at the main header and record baseline consumption during a no-production period (e.g., nights or weekends when equipment is off). Any flow reading during this period represents leakage. You can then isolate sections of the system to locate the source. Typical leak rates of 20–30% of compressor capacity are common in older facilities.

Question 9

Can the kit be used for ongoing monitoring or only for surveys?

Accepted Answer

The kit is designed as a portable survey tool for temporary installation. For permanent monitoring of compressed air consumption, consider a standard RCM gas flow meter (Series 7000 or 8000) permanently installed in the line. The survey kit is ideal for audits, troubleshooting, and energy assessments.
