Benefits and Features Accurate switching flow monitor for water or oil - based solutions up to 100 bar (1,500 PSI) High accuracy even under low flow conditions Separate adjustments for Range and Set-Point Analog display of actual flow and display of adjusted set-point Separate LED for output status ISO 9000 certified manufacturing CE approved Precision and effectivity even at very low flow rates The flow-captor 4120 is a unique, precise, metering flow switch with adjustable setpoint for industrial application. For the first time in flow technology it is possible to set an exact flow set-point and to simultaneously measure flow speed in applications where the use of conventional devices is restricted, due to lack of space, or where the price of such devices is not feasible. The simplicity and convenience in operating or adjusting the new flow-captor sets it apart from similar devices.

Outstanding Features:

Adjustment of the required measuring range between 0-20 cm/s and 0-300 cm/s results in a set-point accuracy, at lower ranges, of 10 times higher than is possible with conventional measuring devices, Simple reading of the actual flow rate. Simple and exact setting of the set-point. The set-point adjustment is relative to the maximum value of range adjusted, which remains the same even when range is altered.

Operating Principle

The flow-captor, type 4120 operates according to a new calorimetric principle, providing a linear measurement of the flow rate in pipe systems up to 3 m/s. The nonintrusive measurement is carried out at a tangent to flow and thus, does not affect flow profile. The max. measuring range of the flowcaptor can be continuously adjusted within a wide range from 20 to 300 cm/s. The linear display of flow is indicated on an LED string. The set-point is set as a relative value to the maximum value of range adjusted, independent of the measuring range and is displayed by a flashing LED within the LED string. A comparator defines the condition of flow, which is simultaneously indicated by a separate LED, by comparing the actual value and the set-point value.

Sensorhead and Housing

The sensorhead is constructed from one piece of stainless steel, which is resistant to most corrosive media, and without any sensor elements intruding into the medium. Installation is by means of a T-fitting or welded nipple. The housing is constructed of glass fibre PBTP (Ultradur) and contains a clearly arranged control and display panel. Practical experience provided a basis for the shape of the housing which optimally combines convenience of operation and durability.

Applications

The flow-captor 4120 can be applied in all areas of industry where exact flow setpoints are required, e.g. in systems where a signal is required at a slight deviation of the flow rate above or below the nominal value. In addition to this, the flow-captor can be applied as an accurately switching flow monitor. There is no industry in which the flowcaptor cannot optimize existing processes.
