Introduction
I. Shipping and storage; product inspection
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. Any damage claim received at a later
time will not be honored.
II. Warranty
Your flow sensor was manufactured in accordance with the highest quality standards and was thoroughly
tested prior to shipment. However, in the event any problem arises with your device, we will be happy to resolve
the problem for you as quickly as possible under the terms of the warranty which can be found in the terms and
conditions of delivery. Your warranty will only be honored if the device was installed and operated in accordance
with the instructions for your device. Any mounting, commissioning and/or maintenance work is to be carried
out by qualified and authorized technicians only.
III. Validity of this operating manual
The present instructions apply to explosion-proof Coriolis flow sensors of the TM/TMU and
TM-SH series, as of year of construction March 2021 or later.
These instructions are supplementary operating manual for non-explosion proof Coriolis flow
sensors. If you do not have a copy of the latter instructions, please request one from Heinrichs
Messtechnik GmbH or download the instructions from our website.
The instructions herein pertain primarily to explosion proof Coriolis flow sensors for use in conjunction with an
explosion proof certified transmitter. The technical data in the mounting and operating instructions for non-
explosion proof Coriolis flow sensors still apply insofar as the present instructions do not replace them or
exclude their application.
The transmitter used in conjunction with a TM/TMU or TM-SH sensor must be listed for use in Canada and/or
USA depending on its area of installation. The manufactures installation drawings shall be followed when
installing this equipment.
Repairs and hazardous materials
It is important that you do the following before shipping your flow sensor to Heinrichs Messtechnik GmbH for
repair:
Enclose a description of the problem with your device. Describe in as much detail as possible the application
and the physical and chemical properties of the fluid.
Remove any residues from the device and be sure to clean the seal grooves and recesses thoroughly. This
is particularly important if the fluid is corrosive, toxic, carcinogenic, radioactive or otherwise hazardous.
The operator is liable for any substance removal or personal damage costs arising from inadequate cleaning of a
device that is sent for repair.

1. 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. These
manuals can also be downloaded from our website.
The TM, TMU and TM-SH sensors described herein are only to be used to measure liquid and gas mass and
volume flow, as well as density and temperature, in conjunction with a transmitter certified for use in the area
and country of operation, and compatible with the parameters of the sensor.
1.1 Installation, mounting, commissioning and maintenance
Installation, mounting, commissioning and maintenance are to be performed by a technician trained to work
with explosion-proof devices, or by a Heinrichs Messtechnik service technician.
Warning:
Any safety relevant maintenance or repairs in terms of explosion-protection is to be
carried out by the manufacturer, an authorized Heinrichs Messtechnik GmbH service
center or under the supervision of an expert in explosion proof devices.
Heinrichs Messtechnik GmbH accepts no liability for any loss or damage of any kind arising from improper
operation of any product, improper handling or use of any replacement part, or from external electrical or
mechanical effects, overvoltage or lightning. Any such improper operation, use or handling shall
automatically invalidate the warranty for the product concerned.
In the event a problem arises with your device, or if you need assistance in diagnosing a problem with your
device, please contact us at one of the following numbers to arrange to have your device repaired:
