SAFETY INSTRUCTIONS 1 SAFETY INSTRUCTIONS 1.1 Intended use MENKAR series level indicators are suitable for continuous measurement and monitoring of the level of a liquid in open or closed containers as required. The liquid level in the container to be monitored is transmitted by a float in a 1:1 ratio as an analogue value. The measurement is independent of the operating pressure. The instruments are noted for their robust construction, trouble-free usage and good readability, even from further away. Various magnetically operated contact units for control and regulation processes (acoustic...

INSTALLATION AND PRINCIPLE OF OPERATION 3 INSTALLATION AND PRINCIPLE OF OPERATION 3.1 Installation notes Information! All instruments are carefully checked for proper functionality before shipment. Immediately on receipt, check the outer packing carefully for damage or signs of improper handling. Report any damage to the carrier and your local sales staff. In such cases, a description of the damage, the type and the serial number of the instrument should be given. Unpack the instrument carefully to avoid damage. Check the delivery for completeness on the basis of the delivery note and the...

INSTALLATION AND PRINCIPLE OF OPERATION The following points should be noted when installing the instruments in the pipeline: »» Remove the transport lock from the valve. »» Before installation, check that the float in the valve can move freely without jamming. 3.3 Installation instructions »» The effective pressure of the installation (the maximum pressure allowed by the pres- sure relief valve) must never exceed the maximum allowable pressure PS indicated on the nameplate. »» The user must ensure that the materials (guide tube, floats, seals, etc.) that come into contact with the fluid...

INSTALLATION AND PRINCIPLE OF OPERATION 3.5 Display of the actual level The float is equipped with a ring system made of permanent magnets in order to transmit the liquid level. For design reasons, the minimum level in the measuring tube is indicated by the axis of the lower lateral connecting flange, i.e. the zero point forms the centre line of the lower connecting flange. In the event of a major change in the product density specified in the order, or when installing another float, the scale on the MENKAR may need to be adjusted to ensure a correct reading. In such a case, please contact...

3.8 Configuration MENKAR level indicators are manufactured in lengths of up to 5,000 mm, depending on the type, and with a split design for longer lengths in order to facilitate transport. The connection is made using flanges. The following points must be observed taking account of the particular operating data and local conditions: »» Type of fitting »» Type and design of instrument »» Length / measuring range »» Scale type (%, volume or height units): For scales in volume units, the user must provide an outflow table. The scale can also be retrofitted and installed by the user. For...
