The RCM INDUSTRIES 1 14 -71-R-100-C is a variable area flowmeter, commonly known as a “rotameter.” It is designed to provide a direct visual indication of flow rate for liquids or gases in a pipeline. The model number indicates specific features for its construction, connection, and measurement range.
Detailed Product Description
1. Manufacturer: RCM Industries
-
A well-known and reputable manufacturer of flow measurement instruments.
2. Product Type: Flowmeter (Variable Area / Rotameter)
-
How it works: The fluid flows upward through a tapered tube, lifting a float (or piston). The height of the float corresponds to the flow rate, which is read against a scale on the tube. It’s a simple, reliable, and cost-effective technology.
3. Key Specifications from Model Number:
-
“1 14”: This refers to the connection size, which is 1-1/4 Inch NPT. This is the threaded pipe connection size for installation.
-
“-71-“: This indicates the meter type and body construction. In the RCM numbering system, the “71” series typically refers to their Piston Type Flowmeters with a Flanged End Connection. This is a crucial detail, as it differs from a simple glass-tube rotameter.
-
Piston Type: Uses a magnetic piston inside a metal metering tube. This makes it more durable and suitable for higher pressures and temperatures than glass tube meters.
-
Flanged Ends: The connections are flanges, not the 1-1/4″ NPT as initially indicated by “1 14”. There may be a discrepancy or a specific configuration here. It’s possible the unit has flanges that are 1-1/4″ in nominal pipe size. The “-R-” is key to confirming this.
-
-
“-R-“: This designates the connection type as “Raised Face Flanges”. This confirms the flanged connection.
-
“-100-“: This is the flow range code. The specific flow rate (e.g., in GPM for water or SCFM for air) must be looked up in the RCM model “100” specification sheet. You cannot determine the exact flow rate from this number alone.
-
“-C”: This is the metering tube and float material code. The “C” typically indicates a 316 Stainless Steel wetted parts, which provides excellent corrosion resistance.
4. Performance Ratings:
-
180 PSI: The maximum working pressure is 180 pounds per square inch. The system should not exceed this pressure.
-
220F TEMP: The maximum fluid temperature is 220 degrees Fahrenheit (approximately 104 degrees Celsius).
5. Scale & Readout:
-
“1-14”: This likely refers to the scale range printed on the meter. However, this is a linear scale (e.g., 1 to 14). The actual engineering units (Gallons per Minute, Liters per Minute, etc.) are determined by the “-100-” flow range code and what fluid the meter was calibrated for.
-
“60 SEO”: This is not a standard industry term. It is most likely an internal customer part number, job number, or a special order code used by the company that purchased this meter.
