Foreword These Installation and Operating Instructions are applicable to devices of Series RA 60 and FA 60. Please follow all instructions and information given for installation, operation, inspection and maintenance. The Instructions form a component part of the device and should be kept in an appropriate place accessible to the personnel in the vicinity of the location.
Intended use The Series RA 60/FA 60 device is a variable area flow meter designed for liquids and gases and for installation in vertical pipe runs. Installation in the pipeline should be carried out solely in accordance with these Instructions.
In accordance with the law concerning handling of waste (critical waste) and the hazardous materials directive (general duty to protect), we would point out that all flow meters returned to Kirchner und Tochter for repair are required to be free from any and all hazardous substances (alkaline solutions, acids, solvents etc.).
● Prepare the installation point for the measuring device with appropriate pipe threads (RA 60) or flanges (FA 60) before beginning installation work. Pay attention to the correct spacing of the sealing faces and to exact alignment.
Installation RA 60 1. Remove the insert (item 1) and the union nuts (item 3) from the device. 2. Slip the union nuts over the ends of the pipeline at the installation point. 3. Screw the inserts using packing material (e.g.
Start-up The device must be properly installed before it is started up. 1. Check all device connections. 2. To set the flow: pressurize the pipelines by slowly opening the shut-off valves. On liquid service: carefully vent the pipeline. 3. Check the leak-tightness of all components and if necessary, tighten down threaded joints or screw connections.
Limit switches MSK1/MSK12/MSKW The flow meter can be equipped with limit switches to provide local indication with monitoring function. The limit switches consist of a limit switch (reed switch) that is switched over by the magnet integrated in the float. The limit switch is guided in a guide slot in the protective case and can be adjusted over the full measuring range.
Setting the limit switches 1. Loosen the lock nut SW13 (M8 x 1) on the neck of the switch . 2. Slide the switch to the flow value required to be monitored. 3. Please make sure the contact never touches the measuring glass and the clearance between contact ...
Linear displacement sensor 4 .. 20 mA/0 ... 10V The linear displacement sensor, based on the Hall effect, delivers an output signal proportional to the height setting of the flow meter. The signal can be displayed in 4 ... 20 mA or 0 ... 10 V and is used for remote flow rate observation.
Adjusting the sensor The linear position sensor is delivered adjusted to the lowest measuring range point. This corresponds to an output signal of 4 mA. The remaining measuring range or mA values can be taken from the supplied protocol. If you want to move the 4 mA value to another measuring range point, move the sensor or the 4 mA value to the requested point.
Maintenance and cleaning of the flow meter The device is maintenance-free. Should the glass cone become fouled, the device can be removed from the pipeline as follows. Dismantling the glass cone RA 60 1. First dismantle the device by undoing the screw connections, item 3.
3. Align the glass cone so that the markings can be read off through the cutout in the case. Replacement of the glass cone RA 60 Proceed as described in section 9.1. and section 9.2 For devices with glass size 6 and smaller, a support disk (20) is additionally installed.
Dismantling of the glass cone FA 60 1. Remove the device together with the gaskets pertaining to the flanged connections (detach the flanged connections). 2. Dismantle the outer flanges, items 1 and 16. 3. On nonguided floats, the float stops (receptacles) in the measuring glass are either helical springs or inserts made of plastics.
Subsequent installation of a float catcher protective cap Pressure surges in the measuring line can cause damage or destruction of the float catch. In order to evenly distribute occurring forces and to prevent tearing of the elastomer, RA/FA 60/65/77/87 series variable area flow meters are equipped with a stainless steel float catch protection cap.
