All devices are thoroughly tested and checked for order compliance prior to shipping. Upon receipt of the device, check it for shipping damage. If any problem comes to light, contact your local Spirax Sarco representative. Please describe the problem and indicate type and serial number of the device. We extend no guarantee of any kind for repair work that is undertaken without notifying us in advance of the intention to carry out such work.
Page 4: Hazard Warnings
Installation, commissioning, operating personnel Mechanical and electrical installation, as well as commissioning, maintenance and operation, are to be realized solely by qualified personnel that are authorized by the installation operator to perform such work. All such personnel must read and understand the content of the applicable operating instructions before working with the device.
Page 5: Proper Use Of The Device
2.5 Proper use of the device Warning The operator is responsible for ensuring that the material used in the sensor and housing is suitable and that such material meets the requirements for the fluid being used and the ambient site conditions. The manufacturer accepts no responsibility in regard to such material and housing.
Page 6: Intended Purpose
ELM DN50 ELM DN150 – DN200 The ELM flow meter range has been designed for use on water / condensate which are in Group 2 liquids of the above mentioned Pressure Equipment Directive. The product’s use on other liquids in Group 1 or Group 2 may be possible but, if this is contemplated, Spirax Sarco should be contacted to confirm the suitability of the product for the application being considered.
Page 7 Packaging, storaging, transport Be careful not to damage the device while unpacking it. The device should be stored in a clean, dry room until it is installed so as to prevent particulate matter from entering the device.

Page 9 4. Steps prior to operation It is essential that you read these operating instructions before installing and operating the device. The device is to be installed and serviced by a qualified technician only. No instructions, wiring diagrams, and/or supplied software, or any portion thereof, may be produced, stored, in a retrieval system or transmitted by any means, electronic, mechanical, photocopying or otherwise, without prior written permission.
Page 10: Operational Mode And System Design
6.2 System design The electromagnetic ELM-*** flowmeter consists of a sensor, which picks up an induced measuring signal from the medium flowing through the pipe, and a transmitter which transforms this signal into standardized output signals (4-20 mA or pulses). The sensor is installed in the pipe while the transmitter is mounted directly on the sensor.

7.5 Ambient temperature range -20°Celsius to + 60°Celsius (-4°F to 140°F) In the case of an outdoor installation, the device must be protected against direct solar irradiation with a weather shield. 7.6 Storage temperature - 25°Celsius to + 60°Celsius (-13°F to 140°F) 7.7 Degree of protection SG2b standard housing, IP68 (NEMA 6P).
Page 13: Process Conditions
7.8 Process conditions 7.8.1 Fluid temperature The data sheet/rating plate of the connected transmitter must be observed. With directly mounted transmitter on the sensor the heat entry must be considered from the process to the transmitter. 7.8.2 State of aggregation Liquid 7.8.3 Viscosity No restrictions.
Page 14: Receipt Of Goods
8. Installation/conditions for use 8.1 Receipt of goods and transport 8.1.1 Receipt of goods Check the packaging and contents for damage. Inspect the supplied goods to ensure complete delivery and compare the consignment with your order specifications. 8.1.2 Transport The protection caps should only be removed immediately before installation of the device in the pipe.
Page 15: Installation Conditions
8.2 Installation conditions The installation location in the pipe must be selected so that the sensor is always fully filled with the fluid and cannot run empty. This can best be guaranteed if it is installed in an ascending pipe or drain. The measuring principle is generally independent of the flow profile of the fluid provided no standing vortices reach into the area where the value is measured, such as downstream from elbows or half-open sliding valves upstream from the sensor.
Page 16: Horizontal And Vertical Installation
8.3 Installation Screws, bolts, nuts and seals are not supplied and must therefore be provided by the operator. Install the sensor between the pipes. Please observe the required torques stated Section 8.3.4. The installation of additional grounding rings is described in Section 8.3.3. Use for the flanges only seals in accordance with DIN 2690.
Page 17: Installation Examples
Installation examples Horizontal lining In order to avoid measuring errors caused Installation in a slightly ascending pipe. by gas pockets and lining damage caused by negative pressure, the following points must be observed: Highest point in pipe system. Air bubbles will accumulate in the tube.
Page 18: Installation Of Pumps
Long pipes Always install regulating and shut-off devices downstream from the sensor. (Danger of vacuum!) Fig. 11 Installation of pumps Do not install flowmeters on the suction side of pumps in order to avoid a negative pressure and damage to the tube lining. Fig.

Page 20 8.3.4 Torques for studs and nuts Electromagnetic flowmeters must be installed in the pipe system with special care due to the fact that the flow pipe lining is made of PTFE which is malleable under pressure. If the flange nuts are tightened too much, the sealing surface will deform. If the seals are supposed to function properly, the correct torque is highly important.
Page 21 8.4 Wiring Caution! Installation and wiring may only be performed when the auxiliary power is switched off. Non-compliance can result in electric shock and irreparable damage to electronic parts. 8.5 Nominal size and ranges Volume flow depends on the flow velocity and the nominal size of the flowmeter. The electromagnetic flowmeter has been designed in such a way that it operates within the range of the flow velocities occurring in practical applications.
Page 22: Ambient Conditions
8.6 Ambient conditions Ambient temperature range For fluid temperatures > 60°C As the sensors are an element of the pipe, these are normally thermally isolated when installed to save energy and prevent accidental physical contact. Due to the process temperature heat is introduced through the support for securing the integral mount transmitter or the terminal box.
Page 23: Ingress Protection
8.6.4 Ingress protection The sensor meets the requirements of the protection class IP 67. The following must be observed to ensure compliance with protection class IP 67 when the device has been installed or serviced: The housing seals must be clean and undamaged when placed in the sealing groove. If necessary the seals must be cleaned or replaced.
