easuring

principle

Capacitive level meters CLM

®

are designed for continuous level measurement of liquids, powders and bulk-solid materials in vessels, tanks, sumps, containers, silos, etc. CLM consists of the stainless steel housing with electronic module and the measuring electrode. Type of measuring electrode is defined by kind of use and type of measured media.

The electronic part converts the capacity into the current signal (4 ... 20 mA) or voltage signal (0 ... 10 V). Sensitivity (SPAN) and initial capacity compensation (ZERO) can be fluently set. CLMs are offered in version (N) for non-hazardous environments or (Xi) version to explosive areas up to zone 0 or zone 20, high temperature performance and several types of process coupling are also available.

ange

of

applications

Capacitive level meters are suitable for continuous level measurement of liquid and bulk-solid materials. CLMs are resistant to any changes in the atmosphere above the surface (vacuum, pressure, vapours, dust). It is also partially resistant to the formation of foam on the surface.

BASIC INFORMATION

Level meters with coated electrode have protection cover at the end of electrode, which is necessary take down before mounting.

Level meters mount in vertical position to upper lid of tank or reservoir by steel welding flange ON-36x2 (steel 11375), stainless steel welding flange NN-36x2 (stainless steel 1.4301), fixing nut UM-36x2 (stainless steel 1.4301) or Clamp flange.

For mounting level meter to the metal tank or reservoir is not necessary to ground housing again.

In case of installation in concrete sumps or silos it is properly to install level meter at metallic auxiliary construction (console, lid, etc.) and then connect with metal all the time submerged object, eventually with steel armouring.

For measuring of material in plastic and glass vessels by level meter without reference tube is necessary to connect grounding screw at housing with auxiliary electrode which is fixed by the appropriate method to the outer casing of vessels (or at inner wall). Material of auxiliary material.

electrode is necessary to choose with consideration to the working environment and properties of measured

For correct function of level type CLM-36N_-40 is necessary to ensure the impedance between of the measured medium and ground. This can be provided by:

1) The medium is isolated from all devices that may cause temporary grounding of the medium

(pumps, valves, connection with the grounded tank by flowing medium).

2) If the first option is not possible, it is necessary to ground the medium permanently.

lectrical

connection

The level meter is designed to be connected to supply unit or to controller through a cable with the outer diameter of 6 ÷ 8 mm (recommended cross-section of cores 0.5 ÷ 0.75 mm

2

) by means of connector which is included in delivery. The scheme and the inside of the connector are on pictures.

Procedure to connect the cable to the level meter:

1. Unscrew connector from the body of the level meter using a suitable screwdriver.

2. Use a flat screwdriver to remove the inner part of the connector (screwdriver into the gap marked by arrow).

3. Unscrew the cable gland and put the cable inside.

4. Connect the cable wires to the screw terminals as shown in Fig. 10 (current output 4-20 mA) or Fig. 12 (voltage output 0-10 V). Tighten the terminals firmly.

5. Push the terminals back into the connector so that the terminal no. 3 is oriented toward the cable entry. Tighten the cable gland.

6. Check the seal on the connector and connect the connector back to the body of the sensor.

The voltage source should be preferably realized as a stabilized power supply unit with safe voltage from

18 to 36 V DC (18 ÷ 30 V DC at version Xi(XiT)), which can be a part of the evaluation or display device.

In case of strong electromagnetic interferences (EMI), parallel cable ducting with power lines, or when cable length exceeds 30 m we recommended to use shielded cable.

CURRENT OUTPUT 4 ... 20 mA

1. Empty tank to the minimum level.

2. By DIP switches on level meter set range

3)

No. 2 (250 pF).

3. Turn by screwdriver in trimmer 4 mA and set quiescent current of the level meter to

4 mA. Turning right wards (in clockwise) increase the current, turning left wards

DIP switches to the nearest higher range and set up of current 4 mA perform at this range. decrease the current. When is impossible to set required current to 4 mA, then switch

4. Fill the tank to the maximum level. When it is impossible fill the tank to the maximum

state then we use some known (measurable) level and current for next setting calculate according to formula:

5. If the output current is less than 20 mA (or the value of I out), set to the lowest range No. 1. by DIP switches and continue to step 7. When the output current reaches

20 mA , continue on step 6.

6. By DIP switches step wise switch to higher ranges till the current is greater then

20 mA (or calculated value I out), through level meter then flows current e.g. 21 mA

Trimmer 20 mA is still in basic position.

4)

.

7. Then set by trimmer 20 mA current of level meter to 20 mA (or to calculated value I out

- see bellow).

8. To reach a maximum accuracy is useful to check over the setting of 4 mA

(compensation of initial capacity - quiescent current).

VOLTAGE OUTPUT 0 ... 10 V

1. Empty tank to the minimum level.

2. By DIP switches on level meter set range

3)

No. 2 (250 pF).

3. Turn by screwdriver in trimmer 0 V and set voltage output of the level meter to

0 V. Turning right wards (in clockwise) increase the voltage, turning left wards

DIP switches to the nearest higher range and set up of voltage 0 V perform at this range.

decrease the voltage. When is impossible to set required voltage to 0 V, then switch

4. Fill the tank to the maximum level. When it is impossible fill the tank to the maximum

state then we use some known (measurable) level and voltage for next setting calculate according to formula:

U out = 0,1 x level in % [V]

5. If the output voltage is less than 10 V (or the value of U out), set to the lowest range No. 1. by DIP switches and continue to step 7. When the output voltage reaches

10 V, continue on step 6.

2) Sensitivity - minimal capacity change of electrode to reach output range 4 ÷ 20 mA or 0 ÷10 V.

3) Range = capacity of housing + activated electrode to reach output range 4 ÷ 20 mA or 0 ÷10 V.

(For example.: uncoated electrode 1000 mm immersion in fuel: 20 pF + 30 pF, coated electrode 1000 mm immersion in water: 20 pF + 500 pF)

4) In case of short of electrode on housing or setting of a very sensitive range can caused to current restriction of level meter on value max. 30 mA.


6. By DIP switches step wise switch to higher ranges till the voltage is greater then

10 V (or calculated value U out), output voltage of the level meter is then e.g. 10,5 V.

Trimmer 10 V is still in basic position.

7. Then set by trimmer 10 V voltage of level meter to 10 V (or to calculated value U out

- see bellow).

Manipulation

and

Maintenance

The level meter does not require any personnel for its operation. Follow-up displaying device is used to inform the technological entity operating personnel on the measured substance level height during the operation.

MAINTAINCE OF LEVEL METER

Maintenance of this equipment consists in verification of integrity of the level meter and of the supply cable. Depending on the character of the substance measured, we recommend to verify at least once per year the clarity of the ultrasound transducer emitting field and to clean it, respectively. In case any visible defects are discovered, the manufacturer or reseller of this equipment must be contacted immediately.

The level meter must be installed to prevent tensile overload of the rope electrode.

It is forbidden to perform any modifications or interventions into the CLM–36 level meter without manufacturer's approval. Potential repairs must be carried out by the manufacturer or by a manufacturer authorized service organization only.

Installation, commissioning, operation and maintenance of the CLM–36 level meter has to be carried out in accordance with this instruction manual; the provisions of regulations in force regarding the installation of electrical equipment have to be adhered to.

REPLACEMENT OF DEFECTIVE ELECTRONIC

In case of detected electronic failure it is possible to replace the electronic module directly in process place of level meter by following procedure:

1. Disconnect connector and unscrew a nut (attention for inside connecting wires).

2. Defective electronic module pick up by pliers onto brass tie and remove by tensile from housing of level meter.

3. Check placing of white seal O-ring in housing and on pressure ring.

4. Repaired or new electronic module return back into housing of level meter and press down by clamping ring (attention that contact pin will be a little open before insertion and contact springs were not pressed under level of electronic casing).

5. Check placing of black seal O-ring on connector.

6. Screw a nut back (attention for inside connecting wires) and connect the connector.

nstallation

For correct function of level type CLM-36N_-40 is necessary to ensure the impedance between of the measured medium and ground. This can be provided by:

1) The medium is isolated from all devices that may cause temporary grounding of the medium

(pumps, valves, connection with the grounded tank by flowing medium).

2) If the first option is not possible, it is necessary to ground the medium permanently.
