IV. Linearity

Influence of the tank shape on a linearity of measured capacity of nonconductive liquids:

1. In the tank with straight wall (for example vertical cylinder) and with the sensor placed

parallely with the wall capacity change is linear.

2. In a curved tanks (most frequently horizontal cylinder) capacity change during

measuring of electrically non-conductive material is non-linear. Linearity is done

by reference tube (CLM-36_ _-20, 22-_).

- 9 -

V. Mounting and dismounting

Level meters with coated electrode have protection cover at the end of electrode, which is necessary take down befere 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 metalic 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 electrode is necessary to choose with consideration to the working environment and properities of measured material.

Orientation of proportion for mounting of level meter (including eventualoly auxiliary electrode) shows following pictures.

VI. Instalation of level meter and placing in operation

Mounting, installation, placing in operation, maintainance, using and service of level meter CLM-36 must be done in conformity with this service manual and has to be performed according the norms for installation of electrical devices.

Electric connection of feeder cable is realized in state without voltage through the use of thread terminal in dismountable connector GDM at level meter’s housing.

Positive pole of supply (+U) will be connected at terminal (1), negative pole of supply

(0V) will be connected at terminal (2) - see following pictures.

Connection scheme of level meter

The inside scheme of the GDM connector socket

+U shielding

0V

Cable from level meter to the further unit is by two-wire cable with outside diameter of

6 ÷ 8 mm (recommended cross section of cores 0,5 ÷ 0,75 mm

2

).

A shielded cable must be only used if the lead is longer than 30 m or in the event that a power line must be used simultaneously with the lead. Connect shielding to the socket , shielding do not connect to the power panel.

Power supply for variants CLM-36N and CLM-36NT can be by stabilized safety voltages power supply 9 ÷ 36 V DC (SELV), example PSU-2400 or DSU-2400.

Or following evaluation device, for example programmable display unit PDU-4xx. For variants CLM-36Xi and CLM-36XiT must be connected with intrinsically safe isolating repeater 9 ÷ 30 V DC, for example IRU-420.

Activation is by turning on of the power supply (for example PSU-2400 či DSU-2400 for variants CLM-36N and CLM-36NT) or intrinsically safe isolating repeater (for example IRU-

420 for variants CLM-36Xi and CLM-36XiT).

VII. Preparing of level meter for measuring

Preparing of level meter

1. For access to the adjustment elements disconnect a connector and unscrew a nut

(attention for inside connecting wires). Connector connect again.

2. Level meter connect to the supply unit through miliampermeter (controler, etc.).

3. Trimmer

2)

20 mA bring into the basic position (this position is set by producer):

a) Turn out trimmer totally rightwards (in clockwise).

b) Return back for 3 turns leftwards.

2) The trimmers are without backstops - approx. 15 turns.

3) Sensitivity - minimal capacity change of electrode to reach a current range 4 ÷ 20 mA.

4) Range - maximum capacity of housing and activated electrode to reach current range 4 ÷ 20 mA.

5) 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.

VIII. Setting with unknown value of permittivity

Setting of level meter with unknown value of permittivity of measured medium

1. Empty tank to the minimum level.

2. By DIP switches on level meter set range

4)

No. 2 (250 pF).

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

4 mA. Turning rightwards (in clockwise) increase the current, turning leftwards

decrease the current. When is impossible to set required current to 4 mA, then switch

DIP switches to the nearest higher range and set up of current 4 mA perform at this

range.

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:

I out = 4 + (0,16 x level in %) [mA]

5. By DIP switches stepwise switch to higher ranges till the current is greather then

20 mA (or calculated value Iout), thru level meter then flows current e.g. 21 mA

Trimmer 20 mA is still in basic position.

5)

.

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

- see bellow).

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

(compensation of initial capacity - quiescent current).

IX. Setting with known value of permittivity

c) Set the possible ranges -

capacity of housing and activated electrode

(C2) will not be greather than range value (R).

C2 < R

d) Sensitivity check - difference of capacity activated (CAE) and non-activated

(CNE) electrode must be greather than sensitivity of calculated range.

C2 - C1 > S (CAE - CNE > S)

e) Choose the range - both previous conditions must be used together c) and d).

2. Empty the tank to the minimum level.

3. By DIP switches on level meter set up pre-counted range.

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

4 mA. Turning rightwards (in clockwise) increase the current, turning leftwards

decrease the current. When is impossible to set required current to 4 mA, then switch

DIP switches to the nearest higher range and set up of current 4 mA perform at this

range.

5. 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:

I out = 4 + (0,16 x level in %) [mA]

6. On preliminary range of level meter set by trimmer 20 mA current of level meter to

20 mA (or to calculated value I out - see bellow). Turning rightwards (in clockwise)

increase the current, turning leftwards decrease the current.

7. To reach a maximum accuracy is useful to check over the seting of 4 mA (compensation

of initial capacity - quiscent current).

Example of calculation:

Level meter CLM-36N-20-M E1000, measured medium is benzine (ε r

= 2,2), distance from wall to level meter with uncoated rod electrode with reference tube is optional.

1.a) Sum of capacity of housing and non-activated electrode:

C1 = CH + CNE = 21 + 51 =

72 pF

1.b) Sum of capacity of housing and activated electrode:

C2 = CH + CAE = 21 + 100 =

121 pF

- 17 -

IX. Setting with known value of permittivity

1.c) Possible ranges:

C2 < R

121 pF < (2) 250 pF, (3) 600 pF, (4) 1200 pF, (5) 3000 pF, (6) 7000 pF,

(7) 18000 pF, (8) 36000 pF

1.d) Check the sensitivity:

C2 - C1 > S

C2 - C1 = 121 - 72 = 49 pF

1.e) Recommended accurate range:

range (2) 250 pF

49 pF > (1) 20 pF,

(2) 30 pF

Level meter CLM-36N-20 with electrode E = 1000 mm by flowage of benzine has capacity
