Coriolis mass flow sensors Supplementary Operating Manual for explosion-proof Flow-sensors Please read the instructions carefully and store them in a safe place OPERATING MANUAL FOR Page 1 of 21 HPC EXPLOSION-PROOF FLOW METERS...
Introduction Shipping and storage The device is to be safeguarded against moisture, dirt, impact and damage. Product inspection Upon receipt of the product, the consignment should be checked for completeness. The data of the device have to be compared with the packing slip and the order documents Notify us of any shipping damage immediately upon receipt of the product.
Steps prior to operation Prior to installation and operation, it is essential that the operator familiarizes himself with all of the instructions and information contained in the manual for non-explosion proof Coriolis flow meters as well as the present instructions. If any part of either manual is missing, contact Heinrichs Messtechnik GmbH to request a new manual.
1.2.1 Danger Means that failure to take the prescribed precautions will result in death, severe bodily injury, or substantial material damage. 1.2.2 Warning Means that failure to take the prescribed precautions could result in death, severe bodily injury, or substantial material damage. 1.2.3 Caution Means that light bodily injury or damage to assets can occur if the precaution is ignored.
Specifications Description of the HPC Mass-Flow Sensor The HPC sensor has an “Intrinsic safety” type of protection and is equipped with the following four independent potential-free and isolated circuits: Excitation circuit Sensor circuit 1 Sensor circuit 2 ...
Mounting and Installation The mounting instructions for the standard sensor also apply to the explosion-proof sensor. 3.3.1 Thermally insulated sensor In explosive atmospheres the sensor may also be outfitted with thermal insulation. However, so not to impair the sensors thermal ratings, the sensors neck cooling ribs of the high- temperature version shall not be included in the insulation.

Installation and commissioning Mounting The mounting instructions for the standard sensor also apply to the explosion-proof sensor. This handbook complements that of the standard sensor. The sensor may only be separately installed and connected with a special sensor cable, whereby the maximum CL and LL of the connection cable must be observed. Refer to the standard operating manual for the connection scheme of the sensor General conditions for safe operation a) If the conditions described in this document are not adhered to or if there is any...
h) The operational wall thickness of the stainless steel flow tubes are < 1 mm. Therefore, in cases where the sensor is operated in zone 1 atmospheres and where zone 0 may be present in tubes, the operator is to ensure that in the area of these tubes, no risk of damage through the medium or mechanical assertion shall occur.
Maintenance and repair work Definition of terms according to IEC 60079-17: Maintenance: defines a combination of any actions carried out to retain an item in, or restore it to, conditions in which it is able to meet the requirements of the relevant specification and perform its required functions.
Recommended inspection intervals Detailed Visual inspection Close inspection inspection Activity 3-month interval 6-month interval 12-month interval Visual inspection of equipment for intactness, If necessary, at shorter intervals removal of dust settlements Check of electrical system for intactness and functionality Check of entire system User's responsibility Fault elimination No repairs or modifications may be performed on equipment that is operated in conjunction...
