• Description

The RPM utilizes reed switches in the instrument’s stem and a permanent magnet in the float. As the float rises or falls with the level of the liquid, the magnet inside the float acts on the reed switches inside the stem and provides a resistive-chain output. The RPM is also available with optional electronics that convert the resistance output into a 4-20mA signal.

• Installation

- Unpacking -

When unpacking the instrument, exercise care not to subject the instrument to mechanical shock. After unpacking, visually inspect the instrument for damage.

- Environment -

The RPM series intruments should be installed in an areas indoors or outdoors which meets the following conditions:

1. The ambient temperature does not exceed -40 0 C to 85 0 C (-40 0 F to +185 0 F) for Class I Divison 2 or -40 0 C to 40 0 C (-40 0 F to +104 0 F) for

Class I Divison 1.

NOTE: It is recommended that a sun shield be installed over the housing if exposed to direct sunlight.

2. The medium temperature does not exceed -40 0 C to 85 0 C (-40 0 F to +185 0 F) for Class I Divison 2 or -40 0 C to 40 0 C (-40 0 F to +104 0 F) for

Class I Divison 1.

3. Relative humidity up to 100%

4. Pollution Degree 2

5. Measurment Category II

6. Altitude 2000 m or less.

7. Locate the sensor away from strong magnetic fields such as those produced by motors, transformers, solenoid valves, etc.

8. The medium is free from metallic substances and other foreign matter.

9. No corrosive gases such as NH

3

, SO

2

, Cl

, etc.

10. No excessive vibration

11. Ample space for maintenance and inspection.

- Location -

Do not locate the RPM sensor near inlets/outlets. If there is surface wave action, then it may be advisable to use a stilling tube. If a stilling tube is used, drill vent holes in the tube and use a spacer bottom mounting bracket to assure the probe is centered in the tube and the float can move without interference.

Wave action will cause signal bounce. Use a stilling tube to provide a smooth output signal.

- Mounting -

The RPM probe must be secured top and bottom. The bottom of the probe can be secured using stainless steel bottom mounting bracket

(p/n 135396) or similar stainless steel mounting method. This bracket is fixed to the bottom of the vessel and the probe stem seats 0.50" inside of it.

Mounting in this way will prevent any lateral movement and prevent the float from coming off of stem during use.

1. Clamp Mounting

The most common method of mounting the top of the RPM probe is by clamping it into place. Top stainless steel mounting bracket part number 125603 or similar can be used. The U-bolt is tightened around the 1.25” stainless steel stem just below the union. The bracket is permanently mounted to the top of the tank. It is important to keep mounting hardware clear of float travel.

2. Flange Mounting

Provide the compatible mating flange on the tank and install using a suitable gasket.

3.

Plug Mounting

Provide the compatible female boss on the tank and install the RPM with a suitable gasket, O-ring, or thread tape.

Note: Ensure that all metal parts are earthed. Check that the sensor tube is connected to the grounding system, and is not isolated from it for any reason (e.g. loose grounding wire connection).

Warning : Because the enclosure of the electronics/terminals of the Float

Level Sensor is made of aluminium, if it is mounted in an area where the use of category 1 G apparatus is required, it must be installed such that, even in the event of rare incidents, ignition sources due to impact and friction sparks are excluded. In the event that the polyurethane float is used, the nonconductive surface of the float may be charged by nonconductive media, ensure that the media is electrostatically conductive.

• Inspection and Maintenance

Periodic inspection is necessary to keep your RPM unit in good working order.

CAUTION! Do not remove the housing cover until the atmosphere is determined to be safe, and the power supplied to the unit is turned off.

Keep the sensor clean.

If sediment or other foreign matter is trapped between the stem and the float, detection errors may be caused.

Inspect probe shaft and bottom weld for any possible holes or leaks.

If possible leak is detected remove probe from service and send to factory for repair.

Inspect O-ring on cover to make sure that it is in good condition.

Never leave the housing cover off. If the cover becomes damaged or is misplaced, replace immediately.
