The 700 Series Flex-FloTM meter is a simple and rugged flow rate indicator for air, water and other transparent fluids. It is particularly well adapted for applications that fall within standardized flow ranges at moderate pressures and temperatures. The 700 Series features a rugged cast aluminum housing with metal threaded connections, a full air tempered glass window and the ability to install the meter in horizontal (left to right) and vertical (up or down) flow orientations – all at an economical cost.
See-Flo® meters are variable area flow rate meters (“rotameter”).
Instantaneous flow rate measurement.
Observe fluid conditions for color, clarity and flow.
Use in horizontal or vertical piping systems.
Individually calibrated for fluid and operating conditions.
User selectable 10:1 turndown flow ranges. (See Meter Rangeability Sizing Tables)
User selectable units of measure including dual units of measure.
No floats to get stuck, tubes to break or dynamic seals to leak.
Low pressure loss.
Simple design with few parts for long service life.
Erdco See-Flo® Series 3100 sight flow indicators show you at a glance, the
color, clarity and flow of liquids in process lines. The large
tempered glass window permits easy observation of fluid
conditions and vane indicator position.
Armor-FloTM meters with integral transmitters provide an ideal combination – a local mechanical flow rate indicator independent of electrical supply with a 4-20 mA two wire loop powered signal output. The output signal is linear within the middle 80% of the range. A response curve is furnished with each flowmeter. Simple design, rugged construction and good value make this the ideal utility fluid flowmeter.
In addition to the performance benefits of the 3400 Series flow rate meter, the 3500 Series Armor-Flo includes switching capabilities. Adjustable flow switches provide positive indication of flow/no flow conditions or may be positioned to establish process limits. In either application the switch captures the indicator preventing movement until the flow rate is within the acceptable range.
The glass encapsulated reed switches are SPDT rated at 0.25 amperes at 120vac (1.5 amperes at 24vdc). This switch is appropriate for use in Class I, Division 2 areas.
3400 series Armor-Flo flowmeters / flow indicators
Measure liquid, gas or steam flow rates in horizontal or vertical pipelines. Armor-Flo meters handle more aggressive fluids that cannot be measured with See-Flo® due to clarity, pressure or where process also requires limit switches or signal transmission.
Rare earth cobalt magnets are used to couple the flow isolated indicator with the vane. There are no shaft connections or stuffing boxes. The internal wedge shape of the Armor-Flo housing is designed for self-cleaning. These features emphasize simplicity and reduce maintenance.
