Installation For best results, the meters may be installed in any position as long as proper piping installation requirements are observed. This includes sufficient support of adjacent piping to minimize the system’s inherent vibration. Unions of the same pipe size and full port isolation ball valves may be installed for ease of removal and servicing of equipment, if necessary. - Page 24 Manufacturer Name: Universal Flow Model Name(s): ME Transmitter Manufacture ID Code: 24692 (6074 Hex) Device Type Code: (E1EF Hex) HART Protocol Revision Device Revision: Number of Device Variables Physical Layers Supported Physical Device Category Transmitter, Non-DC-isolated Bus Device Figure 20: Device Identification 24 | U F M UNRESTRICTED...

1. After the last digit is set, continue holding A2 until “SEt” is displayed. If you want to change the first digit again, do not hold A2. Momentarily press and release A2 and the first digit starts blinking again. 2. When finished recording the new setpoint (“SEt” is displayed), release A2. Release Figure 34: press and release A2 Note 1: Valid setpoint range is 0-100% of full-scale flow.
