Page 5: General Presentation
A choice of electronic from simple transducer to touchscreen PLC/HMI provides process infor- mation (viscosity, density or temperature) through different kinds of output. Various models The MIVI sensor can be assembled in many different ways to match with the process needed pa- rameters. Here are the main designs: general standard sensor;... -

1.4.1 European Pressure Equipment Directive and EMC directive Up to 60 bars, MIVI sensors are in accordance to the article 4.3 of the PED 2014/68/UE. In case of higher pressure, sensors are agreed one by one. The mounting flange is an accessory to be welded on the process line. It means it cannot be indi- vidually certified but has to be certified with the whole process line. -

Page 13: Plane Side Mounting
For some applications and operating conditions it may be advised to install the MIVI without its flow damper. In this case the flow damper must be replaced by the replacement ring that is delivered with most of the mounting flanges. -
Page 14: Practical Advices
(see technical leaflets ref. 320, 328 or 329), that has the same dimen- sions than the flow damper base, must be placed on the head of the MIVI sensor in order to maintain the O-ring(s) and ensure tightness. -
Page 15: Fluid Homogeneity
PTFE, ADLC and enamel coatings as well as special alloys and electropolish finishing are available. For information the sheath of the standard cable of the MIVI sensor is in PVC material and its cable gland is in chrome-plated brass. - Page 16 The minimal bending radius at the flexible pipe (electric outlet) is of 100 mm. A shorter radius can crush the turns, initiate cracks, generate leakage inside of the MIVI, then fail- ure. Don’t knock, pinch, crush, twist or bend the cable. Its minimum bending radius is 100 mm.
