  • Page 8 If non-vertical mounting is required, the deviation from vertical should not exceed 90°. If mounted beyond 90°, the isolation valve may trap steam or hazardous chemicals, presenting a danger to persons servicing the RIM10 Series of rotor insertion flowmeters. These flowmeters should always be self-draining.

  • Page 11: Mechanical Installation

    3. Mechanical installation 3.1 Pipe tapping The pipeline should be prepared for either cold tap or hot tap installations. A cold tap installation involves drilling a hole into a pipeline that has been depressurised and for which service has been shutdown. A hot tap installation involves drilling a hole into a pressurised line without line shutdown and disruption of the process.

  • Page 15 3.2.3 Insertion depth scale reading calculation After tapping the pipe and installing the RIM10 flowmeter, the turbine sensor needs to be properly positioned within the pipe. To determine the proper insertion depth, the scale reading must be calculated. The scale reading is the figure that the top of the cursor should be set to on the depth scale.
  • Page 16 3.2.4 Rotor orientation and final positioning Note: Tighten the nuts above the packing gland to 34 N m (25 lbf ft) to stop leakage around the stem. Do not over tighten! Caution: Do not allow the orientation of the flowmeter or the insertion depth to change after insertion is complete.
  • Page 17 3.2.5 Rotor orientation and final positioning Use the retractor handle to carefully insert the rotor down into the pipe until the calculated insertion depth figure on the depth scale lines up with the top of the cursor. Use a pipe wrench to align the retractor bar assembly so the flow direction arrow on the cursor is in line with the pipe and pointed downstream.
  • Page 18 3.3 RIM10-700 cold tap installation The RIM10-700 is non-retractable and must be cold tapped. Process shutdown and line depressurisation are required for cold tapping. There are two mounting connections available: Flanged or Screwed. 3.3.1 Installation for flanged connections: Step 1 - Tap the pipe, the hole should be at least 50 mm (2") in diameter, nominally 50 mm (2") in diameter.
  • Page 19 3.3.2 Installation for screwed connections: Step 1 - Tap the pipe, the hole should be at least 50 mm (2") in diameter, nominally 50 mm (2") in diameter. Step 2 - Weld thread-o-let to pipe. Step 3 - Important - Attach the tap check tool to the end of the flowmeter stem before proceeding: Attach the flowmeter to the thread-o-let.
  • Page 20 3.3.3 Insertion depth measurement calculation for the RIM10-700 Use the following equation to calculate the insertion depth for the RIM10-700: B = C – I – E – Wt Where: = Installed dimension to be set on the flowmeter. = For G6 rotor 362 mm (14.25") For L1 and G1 to G5 rotors 368 mm (14.50") = For pipe sizes less than 300 mm (12"), inside pipe diameter ÷...
  • Page 21 3.3.4 Rotor orientation and final positioning Caution: Do not force the stem into the pipe. If the stem insertion is blocked, retract and remove the flowmeter from the pipeline, checking to make sure the opening conforms with the guidelines listed in the mounting guidelines. Manually insert the stem into the pipe until the calculated insertion depth is obtained.

  • Page 22: Electrical Installation

    - Virtual front panel display and set-up wizard using Internet Explorer 6.0 or later on a standard PC The electronics within the RIM10 Series rotor insertion flowmeters are housed in a cast aluminum condulet housing. The condulet is rated for Class I, Div II environments. All field wiring to the flowmeter is connected to the terminal blocks and RJ-45 network port located beneath the rear screw cover (opposite end to the display).

  • Page 23: Ground Loops

    4.1.1 Ground loops Ground loops may interfere with signal transmission by superimposing unwanted signals on the desired signals. This may be prevented by correctly connecting the cable shields. Metal or plastic pipelines determine the shield to be used. Metal pipelines are usually earth grounded. Thus, the cable shield should not be connected at the flowmeter.

  • Page 25: Pulse Output

    4.2.1 dc power Wire the dc power as shown in Figure 20 using 0.82 mm - 0.33 mm (18 - 22 AWG) gauge wire. The dc supply can be anywhere from 12 - 32 V, but 24 V is recommended. On installation the RIM10 shall be provided with supply transient protection external to the apparatus such that the voltage at the supply terminals of the RIM10 does not exceed 140% of the voltage rating of the equipment.
  • Page 26 4.2.3 External 4-20 mA current loop output Three output channels are available for connection. These are 2-wire current loop connections. The positive side is connected to the 24 Vdc supply at pin 7. The negative side is connected to the 4-20 mA receiver input terminal. The receiver should have the common or ground terminal connected to the power supply ground as shown in Figure 22.
  • Page 27 4.2.5 4-20 mA current loop multiple inputs and outputs It is not altogether obvious how to wire multiple 4-20 mA current loops without inserting too many wires into the 24 V and GND terminals. One technique is shown in the following wiring diagram - Figure 24, which depicts the worst case, which is 3 inputs and 3 outputs at the same time.

  • Page 28: Relay Output

    4.2.6 Relay output There are 2 single pole double throw relays available. Each has a normally-closed and normally-open contact which can be wired as shown in Figures 25 and 26. These relays provide resistance of 35 ohms maximum and switching times of less than 1 millisecond. They are limited to 120 mA of current and 350 V blocking voltage.
  • Page 29 4.2.7 RS485 communications A single 2-wire RS485 half-duplex communications channel is provided, and can be used as a Modbus RTU. Wiring is as shown in Figure 27. Caution: Please note that EIA standard 'B' and 'A' terminal labels are used, which are opposite those used by some transceiver manufacturers (for example, Texas Instruments), so care must be taken to not invert the polarity of the signal wires.

  • Page 30: Remote Mount Option

    4.3 Remote mount option The remote mount option allows the main RIM10 electronics to be mounted at a distance from the RIM10 flowmeter at the pipe. The main electronics may be separated from the flowmeter by up to 30.5 m (100 ft) of wiring. Standard shielded twisted-pair cable (Category 5, 5e or 6) is recommended.
