3.4.3 Quick Configuration: configuration examples The minimum functions (fct.) to be configured for a simple measurement are listed below: Tank Height • 1.1.1 • 1.2.1-6 Display Functions • 1.4.2-3 Entry Code 1 / Code 1 • 1.3.1-4 Current Output 1 (& 2) • 1.7.1-2 Volume calibration* *For volume measurements Example procedures for each set of functions are given on the following pages. Each procedure is given in a series of steps in table form and begins from the Operating Mode.
Tank height Configuration Mode user function 1.1.1 This function is usually either defined as true tank height or as factory configured probe length, L1 if the former is not supplied by the customer in the order. Why change the tank height? • • setting the parameter in Function 1.1.1 to L1 avoids having a non-measurable zone underneath the probe where the measurement on the display freezes.
How to configure displayed value and units User Sub-menu 1.2 - Display Functions These functions are used to choose the information to be displayed in operating mode: • the measurement function (distance, level, volume, etc.) and units (mm, ft., m3, etc.
How to protect gauge configuration User menu functions 1.4.2 Entry Code 1 & 1.4.3 Code 1 These functions are used to activate the restricted-access code and lock the settings: these will be impossible to modify without entering the correct code. Do not lose this code! Example procedure 3A: • to activate access code function, • to enter new code and exit configuration mode. Step Action 1 Start from Operating Mode screen Go to function (fct.) 1.4.
How to set an analogue current output scale User menu functions 1.3.1 to 1.3.4 (& 1.3.5 to 1.3.8 for a second analogue output) This set of functions allows users to set up a scale. The minimum (4mA) and maximum (20mA) values of an analogue current output should ideally lie within the device’s active measuring zone, as the display will freeze when the signal is lost. Refer to the measurement limits table for each probe type in the introduction. Refer also to the stqrt of section 3.4.
How to configure the gauge to give volume readings User menu functions 1.71, 1.7.2 & 1.7.3 The BM100 A may be calibrated to measure volume by using a 50-line “strapping (calibration) table”. The shape of the tank decides the number of points to be entered for accurate measurement. Do not set User menu function 1.3.1 or 1.3.5 to “Volume” until steps 1 to 4 have been completed.
Clearing the current gauge volume calibration table data 1. 2. 3. 4. 5. Go to fct. 1.7.3 DELETE TAB. Press “right” to enter the data set field. This will read “SURE No”. Press “up” to select “SURE Yes”. Press “enter” to confirm clearing the “strapping table”.

3.4.6 BM100A TDR level meter characteristics This subsection explains : • the four principle configurations for setting up a measurement scale and what the user should be aware of in each case • what happens when the tank is full or empty. • what are level and interface thresholds and how to modify them, • what happens when one product is measured in interface mode The measurement scale: four possible configurations for analogue current output - with “Level” selected in function 1.3.1 (Function I.
Configuration D Parameters: Function 1.1.1 = True tank height Function 1.3.3 (4mA) = 0.0 Function 1.3.4 (20mA) = True tank height (1.1.1) This combines examples B and C. Care must be taken when the product rises into the top dead zone or drops into the bottom non-measurable zone as TDR gauges cannot monitor in these zones. The configurations given above also apply when “distance” is selected in function 1.3.1 (after adaptation of parameters entered).
Gain and voltage amplitude As explained in the measuring principle in section 7, the level of a product is converted from a return signal (the product reflection) received by the gauge: this signal has taken a certain amount of time to return to the gauge and it has a certain strength / size measured in milli-volts (dependant on the dielectric constant of the product).
Level measurement: Level pulse amplitude and threshold After connection to a power supply, the BM100 A will: 1. Measure reflection pulses in terms of voltage amplitude by cycling through a set of gains. 2. Identify the highest amplitude as being the product level. The diagram below shows a level threshold of 2.71 Volts for a Gain of 1. 1 2 3 4 5 6 7 Initial pulse Flange reflection (except coaxial probe) Non-product reflection (e.g.
If the level pulse is too high 2 solutions are possible: • Modify user function 1.5.3 Detection Delay ignore all signals near the flange Increase the configured value. This will force the gauge to ignore reflections in the distance set from the flange. Note that this will reduce the measurement range. • Modify user function 1.5.1 Level Threshold: to reduce interference along the probe length Increase the voltage amplitude manually in Fct. 1.5.1.
Solid application notes Most dry solid applications except powder or flakes with high dielectric constants, such as charcoal and coal powder, are measured with a Gain of 3. If it is difficult to measure level at a certain point with the gauge using a Gain from 0 to 2, then an internal tank structure (exposed girder, etc.) is most likely to be within the electromagnetic pulse field area : the gauge will detect the largest signal and assume this is the product level.

4.2.2 Basic Servicing – Replacing fuses and the electronics chassis BM100 servicing by the customer is limited by warranty to the removal and replacement of : • the power supply fuse • the electronics chassis. Other repairs must be done by KROHNE-authorised service staff. Removing the electronics chassis Before changing the electronics chassis remember to save the current configuration of the instrument : • Note the settings on the configuration record supplied in appendix B or • Save the settings in a *.
Step 6 Undo the two screws holding block in the housing. Step 7 Disconnect interface socket. Remove display screen circuit board. Step 8 Remove the electronics chassis carefully. Step 9 Disconnect the coaxial cable. Step 10 Use these instructions to mount the new chassis. Care should be taken when putting the electronics package back into the housing to avoid trapping the coaxial cable between the housing and the rear cover. Load the old settings saved on a *.
Replacing the fuses As indicated in the diagram below, the power supply is protected by a fuse, F1. This will be visible when the electronics chassis is removed from the housing. The fuse rating is dependant on the type of power supply used and is given below : Power Supply Board 100 / 240 V AC Power supply fuse F1 T 400 mA / 1500 A (250V) IEC127-2/V Time Lag Fuse Power Supply Board 24 V DC / AC Power supply fuse F1 T 1.

7 Measuring Principle The BM100 A has been developed from a tried and tested technology called “Time Domain Reflectrometry” (T.D.R.). Other modern applications include checking for and locating damage along telecommunication cable lines. The BM100 A sends low-power electromagnetic pulses of one nanosecond width along a rod or cable conductor. This pulse travels at a known speed : the speed of light.
The BM100 A can determine level in two ways, depending on the dielectric constant of the product: Direct mode: Level and / or interface measurement, for products where the dielectric constant is above1.4*. Direct mode: Inverted interface measurement is dealt with in the Service Manual. Tank bottom following (TBF) mode: Level measurement, for products with low dielectric constants (below 2.1) TBF level measurement is explained in the Service Manual.
Simultaneous interface & level measurement of two products Interface can be measured when the top liquid has a lower dielectric constant than the second one. The residual pulse left over from the reflection from the top liquid surface is used for measuring interface distance. This residual pulse continues along the probe until it is reflected by the liquid / liquid interface. The speed of the electromagnetic pulse through the top liquid is determined by the top liquid’s dielectric constant.
