It can withstand submergence in accordance with IP68/NEMA 6P and preferably has an epoxy paint exterior.

(45) A preferred method of assembly of the present invention is as follows: beginning with a pipe 25 (preferably metal) that has a flange 35 already attached (preferably welded) on either end of pipe 25 and with at least one boss 300 already attached to the pipe (preferably welded to the pipe). Threaded studs that will attach magnetic coils to pipe are welded to pipe already. Magnetic coils 400/metal rings 66, 67 are affixed to pipe 25 and are held in place with brackets placed over threaded studs.

(46) Then, pipe 25 is lined with a liner 30. Preferably, the lining process is as follows: pipe 25 goes into the oven which is heated to about 500° F. and stays there for about 15 minutes (the temperature is checked with an infrared thermometer). The pipe 25 is pulled out of the oven and liner 30 is mechanically affixed to the metal tube/pipe 25 via heat shrink (no adhesives). In a preferred embodiment of the present invention, a single piece of partially stabilized magnesium zirconia ceramic liner is preferably mechanically affixed to the metal tube/pipe 25 via heat shrink (no adhesives). A stop is used to ensure that the liner is offset about 0.05″ from both flange ends. The temperature is checked, preferably with an infrared thermometer, until it is below 150° F. Then, holes are drilled out preferably with a diamond sleeve drill and preferably using the bosses 300 for alignment. In a preferred embodiment, the pipe has 4 bosses 300 affixed to it, and the holes are drilled in the now lined pipe using the four bosses for alignment (preferably, 2 of these bosses are for ground electrodes and 2 bosses are for sensing electrodes).

(47) Then, the ground electrodes 590, preferably 2, are welded into place into bosses 300. Then, the sensing electrodes 580 are installed. The electrode wiring circuits of all electrodes, ground and sensing, are completed.

(48) Shell/case 40 will be affixed to (preferably welded to) magnetic coils 400, and the leads from the coils and electrode wires come up through the neck of the shell. And then the junction box is bolted to the neck.

(49) The wires are all soldered to a two board PCB (printed circuit board) stack that has the wiring terminals. Then the neck is potted with epoxy to protect the coils, electrodes, and associated circuitry from water ingress. Next, the meter is flow calibrated, which is when a calibration constant is developed that allows the meter to function with whichever transmitter/secondary the customer specifies: Rosemount, Endress+Hauser, Yokogawa, etc., etc. The meter is then painted, prepped, and shipped.

(76) https://www.hilscher.com/fileadmin/cms_upload/en-US/Resources/pdf/netTAP_NT_50_-_Gateway_Devices_UM_12_EN.pdf

(77) As an example of a system of the present invention, one could include a TECO SAM as described herein, the black box mentioned above, and a Badger Meter Inc. magmeter secondary that has a Profibus DP output connected to the Hilscher NetTap NT 50. The NetTap NT 50 will translate that ProfibusDP signal and can have a PROFINET output.

(78) The inventors developed this system in an effort to solve a customer problem (how do I use TECO's SAM if I have standardized on PROFINET as my communication protocol?). That customer may use a different set up that consists of a magmeter secondary from Endress+Hauser that that has a ProfibusDP output. The black box allows a different magmeter secondary to be used for customers desiring a PROFINET output.

(79) It is possible and advantageous at times to supply both the TECO SAM primary and a secondary appropriate for a customer. Sometimes this system will include as well the black box mentioned above or a different black box with different translating componentry. Sometimes in a single kit there will be the TECO SAM primary and a secondary appropriate for a customer, and single packaging of the magmeter secondary and the translating componentry with a PROFINET output.
