RCM Flow Meter Available Options & Adders
The following is a listing of available RCM flow meter options which include limit switches, transmitters, digital indication and more.
|Options A, B or B2: O-Ring Seals
O-Rings are used to seal internal flanged joints. Standard O-Ring material is Buna-N which is suitable for a wide range of liquids and gases. If no option is specified, Buna-N will be furnished. If Buna-N is not satisfactory, then Viton, EPR or Teflon seals may be suitable. A = Viton seals, B = Ethylene Propylene (EPR) seals, and B2 = TFE seals. E.I. dupont
|Option N: Ammonia Service
This option includes a brass free construction throughout, EPR seals, a stainless steel gear movement and gasketed case. Price includes calibration to specific gravity, pressure and temperature compensation. This option is available for model 73 ONLY.
|Option C: Calibration for Specific Gravity
All Series 7000 Flo-Gages are normally calibrated for water with a specific gravity of 1.0 (density of 62.4 lbs./ft³). If fluids of different density are to be metered, the meter will require either a correction factor or calibration for the desired specific gravity.
|Option P: Panel Mount
This option provides a special meter case for mounting on panels. This option is available on 1-1/2″ and smaller meters only.
|Options D & D2: Gasketed Meter Housing
Standard meter housing protects the meter mechanism against normal dirt and dust. If the meter is to be exposed to the weather, marine service, splashing liquids, corrosive vapors, or extreme humidity or dusty conditions, then a gasketed meter housing is recommended. Gaskets of neoprene sponge are installed at the body flange, back cover plate and under the dial crystal to make the housing leak-tight. Option D2 includes a condulet.
|Option RW3: Digital Readout/Totalizer
Digital display flow meter 2 wire loop powered 4-20mA DC transmitter features 7 digits for flow rate and 11 digits for accumulated total. On-screen engineering units are easily configured, while different units for flow rate and total can be displayed simultaneously. A wide selection of options further enhances this models capability. Optional backlighting is available for easy viewing and intrinsic safe approval for hazardous locations.
|Option E: Non-Standard Flow Rates
Various full-Scale flow rates are available for each pipe size as indicated in the chart of Standard Flow Rates and Body Sizes. These standard flow rates meet nearly all industrial applications and comply with good engineering practice in piping design. However, if smaller flow ranges are necessary, special orifices can be furnished. Consult with us if this is a desired option !
|Option R2: Remote Readout
Adapters and 3-way equalizing valve (Bronze) provide extended temperature ranges or remote mount for more convenient viewing.
|Option ES: Low Flow Rates
A low flow meter is available with ½” female NPT connections for measuring the flow of liquids as low as 1 GPH and gases as low as 10 SCFH. A minimum inlet pressure of 10 psi is required for liquids and gases. Accuracy is ±5% of full scale.
|Option R3: Remote Readout
Adapters and 3-way equalizing valve (316SS) provide extended temperature ranges or remote mount for more convenient viewing.
|Options F & F2: Aluminum Housing
Option F changes the housing from the standard ABS plastic to Aluminium housing with a plastic dial crystal. Option F2 changes the housing from the standard ABS plastic to Aluminium housing with a glass dial crystal.
|Option T: Expanded Temperature Range
Materials suitable for a range of 80F to 350F are provided. Higher temperatures available in combination with Option R2
|Option G: Custom Scales and Dials
Non-standard flow rates and custom dial patterns require preparation of special artwork and stencils. A one time charge is made for each custom dial pattern or non-standard scale.
|Option V: Calabrate for High Viscosity Liquids
Liquids having high viscosities cause flow meters to read high; however, this effect is slight for liquids having viscosities less than 5 centipoises. Heavy lubricating and fuel oils with viscosities up to 500 cps require special sizing of the flow meter orifice. Flo Gages are not recommended for metering of fluids with viscosities greater than 500 centipoises. Consult with us for specific recommendations.
|Option H: 400 psig Service
Standard meters are equipped with bellows which have a service rating of 180 psig maximum. High strength bellows made of Inconel 718 are available with service ratings to 400 psig and may be used where service conditions permit use of stainless steel. A slight increase in pressure drop across the meter results when these bellows are used. International Nickel Co.
|Option W: Transmitter 4-20mA dc 4 Wire Transmitter with Linear Output.
Option W2: Transmitter 4 -20 mA dc 2 Wire Transmitter with Local Mechanical Indicator.
Option W3: Transmitter 4-20 mA dc (same as W2) but without Mechanical Indicator (Blind Transmitter)
|Option I: Compressed Gas Service
Meters intended for compressed gas service require individual sizing of meter orifices to suit the desired flow rate, gas composition, line pressure and temperature. In addition, dials are marked with type of gas, specific gravity, line pressure and temperature as part of this option.
|Option X: Two set point relays (Hi/Lo)
Option Y: 0-1000 Hz frequency output
Option Z: Combines options W, X and Y
|Option J: Peak Flow Indicator
A second pointer is provided with a reset knob to provide an indication of the maximum flow rate achieved since reset.
|Option 1S2: 1 SPDT REED switch
Option 2S2: 2 SPDT REED switches
|Option K: Saturated Steam Service
The steam service option includes EPR seals, SS bellows and inverted housing. Steam pressures are limited to 120# saturated unless remote (option R2) is used. Temperature range: -80° F to 350° F
| Option EM: CE Marking Directive Electromatic Compatability (EMC) Directive 89/336/EEC
Option IS: CE Marking Directive Intrinsic Safety Atex Directive – 94/9/ED:CSA/NRTLc. Not available with options RW3, W,X,Y or Z.
Accessories & Additional Options
Cleaned for Oxygen Service: Cleaning for oxygen service; cleaned in accordance with ASTM G93-96; Inspected per 22.214.171.124, packaged and bagged in polyethylene bags per 12.1.3.

Standard: Meters with non-standard flow rates are calibrated with water at a flow rate calculated to provide the proper differential pressure. These meters are tested at full scale and 50% scale to verify proper operation and accuracy. Certificates of calibration for non-standard flowrates are available upon request at no charge.
Optional: Test standard flow rate meters at full scale and 50% to verify proper operation and accuracy. Includes certificate of calibration. Must be ordered with meter.
Special: NIST traceable 5 point flow calibration certificate and error curve. Water test media only, 4 GPM to 200 GPM full scale. Calibration at time of production
