- Page 8 Note: While installations directly into a 1”metal fitting are not recommended, acceptable results may be obtained if the 1” fitting is a half coupling in form and the outer diameter of the coupler is tightly wrapped in vinyl tape to dampen vibrations. For installations in open tanks and sumps: LM52‐1850 1) Use Flowline's LM50‐1001‐1 side mount bracket. Note: The Side Mount Bracket (LM50 series) is not designed for use with stand pipes or as a method to secure stand pipes. There are too few threads to properly hold the sensor and the stand pipe. LM50‐1001 ...
- Page 9 Mounting with a Stand‐Pipe: A stand‐pipe may be used to dampen turbulence, separate surface foam from the point of measurement or increase performance in heavy vapor. When mounting the sensor in a stand‐pipe, the minimum diameter of the pipe is 2”. Larger diameter pipes can be used. The pipe should be attached with a coupling and reducer bushing. The pipe length should run the measurement span and the bottom of the pipe should remain submerged at all times to prevent foam from entering the pipe. Cut the bottom end of the pipe at 45° and drill a 1/4”pressure ...
- Page 10 Wiring the EchoSonic® II After mounting the sensor, make the necessary electrical connections. A wiring diagram with specific recommendations for the sensor’s configuration can be printed from the WebCal program. A typical wiring diagram is shown on the next page. Red (Power) and Black (Return) leads are for connection to a 24 VDC power supply or to a 4‐20 mA loop power source. The red and black wires can be extended more than 1000 feet using 22‐gauge or larger wire, however do not extend the green and white wires. White (Tx) and Green (Rx) leads are reserved for use with WebCal and should not be connected during usage in the application. These wires should not be connected to WebCal while power is supplied from any source other than the LI99‐2001 Fob. ...
- Page 11 Wiring the EchoSonic® II The following wiring diagram can be used when wiring to the EchoSonic® II relays. Typical Wiring Diagram Your WebCal Wiring Diagram may vary. General notes for electrical connections, usage and safety: Where personal safety or significant property damage can occur due to a spill, the installation must have a redundant backup safety system installed. Wiring should always be completed by a licensed electrician. Supply voltage should never exceed 28 VDC. Protect the sensor from excessive electrical spikes by isolating the power, whenever possible. The sensor materials must be chemically compatible with the liquids to be measured. Design a fail‐safe system for possible sensor and/or power failure. Never use the sensor in environments classified as Hazardous. ...
