This product is covered by one or more of the following patents: 6,431,011 and 6,463,807. ADDITIONAL REQUIRED HARDWARE All GREYLINE insertion type meters can be installed and removed via a 1” or larger full port ball valve without system shutdown. The terms “Standard”... -
Page 8: Additional Hardware That May Be Required
Grounding rings placed before and after the meter eliminate electrical noise that will interfere with the proper operation of the meter. GREYLINE provides grounding rings as an optional accessory. Grounding ring dimensional information and part numbers are listed below. For proper operation, grounding rings are required before and after the meter. -
Page 9: Unpacking
The sensor head should have a smooth continuous surface that is free of abrasions. All GREYLINE products are shipped insured unless the customer specifically requests otherwise. Please notify the shipping company and GREYLINE immediately if any items are damaged in transit. Save all packing material for inspection by the shipper. -
Page 10: Installation, Removal & Adjustment
Please read all instructions before attempting to insert or remove a flow meter. GREYLINE will be happy to assist with technical recommendations and to provide guidance by telephone or e-mail. On-site field engineering, installation and service is also available at additional cost. - Page 11 • Acceptable to install in vertical pipe • Position meter anywhere in upper 240° for horizontal pipe CLEARANCE REQUIRED FOR INSTALLATION 30” - 40” (76 - 100 cm) Depending on pipe size 5 Dia.

Page 12: Mechanical Installation
CAUTION GREYLINE insertion style flow meters must be installed through a valve assembly. Failure to do so negates the ability to remove the meter without shutting down and draining the system. It will also result in an excessive amount of stem protruding from the pipe. Excessive stem lengths unnecessarily expose the meter to incidental damage. -
Page 13: Installation Kit
GREYLINE offers a wide range of installation hardware kits for commonly used pipe 3.2.1 Installation Kit materials. The kits are specifically designed for GREYLINE flow meters, and their use is recommended. The use of GREYLINE installation hardware kits accomplishes two important objectives. -
Page 14: Customer Supplied Installation Hardware
CAUTION In order to provide the flow meter with the correct stem length, GREYLINE must know the over- all height of the installation hardware as measured from the outside wall of the pipe to the top of the valve where the meter is installed. -
Page 15: Confirming The Stack Height
Flow meter stems are intentionally oversized to allow for variations of at least 2” in the stack height. Contact GREYLINE prior to installation if there is any question regarding stack height or stem length. This way GREYLINE can offer you credit for your meter if you decide to exchange the meter for one with a different stem length. -

INSERTION OF THE METER WARNING SYSTEM MAY BE UNDER HIGH PRESSURE. When adjusting the meter position or removing it, be sure to hold the electronics enclosure firmly by hand before SLOWLY loosening the positioning clamping nut. Failure to do this will allow the pressure to suddenly and rapidly force the meter from the pipe causing serious injury. -

REMOVAL OF THE METER WARNING SYSTEM MAY BE UNDER HIGH PRESSURE. When removing the flow meter, be sure to hold the electronics enclosure firmly by hand before slowly loosening the positioning clamping nut. Failure to do this will allow the pressure in the pipe to suddenly and rapidly force the meter from the pipe causing serious injury. -
Page 20: Wiring Connections
Additional cable may be purchased from GREYLINE that will allow you to maintain the existing color coding. All electrical connections to the ISM 5.0 must be made through the 25ft cable provided with the meter. This cable is not designed to be removed in the field, and any attempt to do so will compromise the weather tight integrity of the enclosure. - Page 21 Wire Description Note Color 24±4 VAC 50-60 Hz @ 250 mA or Connect to 24VAC transformer or +24±4 VDC @ 250 mA DC power supply positive Connect to 24VAC transformer common Black (-) Isolated supply common or DC power supply common Green / See Section 3.5.2 for assistance in Earth connection (required to operate)

Page 22: Earth Connection
3.5.2 Earth Connection ISM 5.0 Insertion Magmeters are designed to detect microvolt signal levels at the electrodes located on the sensor head. These signals are generated as conductive fluids flow through the magnetic field generated by the meter. If enough random electrical noise is present at the electrodes, it can interfere with the flow measurement. -

All wiring connections should be made at the end of the factory cable. Do not attempt to remove the factory installed cable or change the orientation of the electronics enclosure. Never connect power to analog or frequency output signal wires. GREYLINE ISM 5.0 Flow meters are not “loop powered” devices. Page... -

(or scale factor) identified on the calibration tag & certificate. Confirm connection to Confirm that the flow meter serial number matches the GREYLINE display or Btu meter correct GREYLINE display serial number (when ordered together). or Btu meter (if ordered). -
Page 25: Start-Up And Commissioning Worksheet
START-UP AND COMMISSIONING WORKSHEET Please read all installation instructions carefully prior to proceeding with these steps. Use the following worksheet for checking off the commissioning steps and recording measured values. The following steps require flow in the pipe. Flow signal readings should be taken while holding the flow rate constant, if possible. -

Btu meter 4.4.1 Earth Connections & Electrical Noise Reduction ISM 5.0 Insertion Magmeters are designed to detect microvolt signal levels at the Introduction electrodes located on the sensor head. These signals are generated as conductive fluids flow through the magnetic field generated by the meter. If enough random electrical noise is present at the electrodes, it can interfere with the flow signal measurement. - Page 27 The most effective way to minimize the effects of electrical noise is to make sure that Minimizing Electrical Noise the pipe, the fluid and the flow meter body are all connected to earth ground. This accomplishes two important goals. First, it ensures that the pipe, fluid and flow meter are all at the same electrical potential.
