2. Volume measurement

A conversion table (strapping table) function is

available in the configuration menu for volume or mass measurement. Up to 30 volume values can be related to level values. For example:

Level 1= 2 m / Volume 1= e.g. 0.7 m³ Level 2= 10 m / Volume 2= e.g. 5 m³ Level 3= 20 m / Volume 3= e.g. 17 m³

This data permits the device to calculate volumes between strapping table entries.

1.3 Product family

OPTIFLEX 1100 C

for continuous measurement of liquids and solids up to 16 barg (232 psig) and +100°C (+212°F)

OPTIFLEX 1100 C is a 2-wire TDR level transmitter for measuring distance, level, volume and mass of liquids and solids. Its simple, compact design allows technicians to quickly assemble the probe and attach it to a threaded connection. It is an affordable solution for applications that do not require a high level of accuracy and is also an excellent alternative to traditional level controls such as RF Capacitance, conductive and DP transmitters.

It is ideal for level measurement in buffer tanks, collectors and simple process applications and silo level monitoring in quarrying and agriculture.

OPTIFLEX 7200 C/F/S/D

PRODUCT FEATURES 1

The device transmits low-intensity electromagnetic pulses of approximately one nanosecond width along a rigid or flexible conductor. These pulses move at the speed of light. When the pulses reach the surface of the product to be measured, the pulses are reflected with an intensity that depends on the dielectric constant, εr, of the product (for example, water has a high

dielectric constant and reflects the pulse back to the signal converter at 80% of its original intensity).

The device measures the time from when the pulse is emitted to when it is received: half of this time is equivalent to the distance from the reference point of the device (the flange facing) to the surface of the product. The time value is converted into an output current of 4...20 mA and/or a digital signal.

Dust, foam, vapor, agitated surfaces, boiling surfaces, changes in pressure, changes in temperature and changes in density do not have an effect on device performance.

The illustration that follows shows a snapshot of what a user would see on an oscilloscope, if the level of one product is measured.

The dielectric constant of the top liquid must be less than the dielectric constant of the bottom liquid. If not, or if there is too small a difference, the device may not measure correctly.

1Time 0: The electromagnetic (EM) pulse is transmitted by the converter

2Time 1: The pulse goes down the probe at the speed of light in air, V1

3Time 2: Part of the pulse is reflected at the surface of the top liquid, the remaining pulse goes down the probe

4Time 3: Part of the pulse goes up the probe at speed, V1. The remaining pulse goes down the probe at the speed of light in the top product, V2

5Time 4: The converter receives part of the pulse and records the signal. The remaining pulse is reflected at the interface of the 2 liquids

6Time 5: The remaining pulse goes up the probe at speed, V2

7Time 6: The remaining pulse goes up the probe at speed, V1

8Time 7: The converter receives the remaining pulse and records the signal

10The EM pulse moves at speed, V2

11Transmitted EM pulse

12Received EM pulse (distance to the top liquid)

13Received EM pulse (distance to the interface of 2 liquids)

Level measurement principle (TBF measurement)

If products have a very low dielectric constant (εr <1.6), only a small part of the EM pulse is

reflected at the surface of the product. Most of the pulse is reflected at the probe end. TBF (tank bottom following) mode is used to measure the distance to the product surface.

TBF mode (indirect measurement) compares:

•The time for the pulse to go to the probe end and go back to the converter when the tank is empty.

•The time for the pulse to go to the probe end and go back to the converter when the tank is full or partially filled.

The level of the product in the tank can be calculated from the time difference.
