Level Transmitters

Product Details:

For constant and non-contact level of measurement in liquids, pastes and coarse bulk materials and for measuring the flow in open channels, such a device is widely put in use.

Working Principle:
Ultrasonic level of instruments are made to operate on the basic principle of making precise use of sound waves, in order to determine the level of liquid/ solid/ slurries. Further, other than the standard level measurement or volume measurement, open channel flow can be monitored and the exact volumetric throughput can also be verified in lift stations. Besides, with such a device in place, we can also measure differential level and can control the pumps.

In grander scheme of things, Minimum measuring distance denoted as Xm and which is also known as the “Dead Band” becomes the most regular feature to all ultrasonic level meters. Such is the limited range in front of the sensor within which the ultrasonic device can never measure. Maximum measuring distance (XM), such is the longest range under ideal condition under which the device can carry out the measurement. However, with the help of such device, differential level can also be measured and pumps can be controlled too.

For the purpose of efficient handling and indicating of processes, Trumen field mounted level indicator model ICT is widely put into use.

Working Principle:
To indicate and control the material level in the process tanks, Trumen field mounted level indicator model ICT is widely being relied upon. ICT is termed ideal for analogue inputs and it provides 4/5 Digit Seven Segment LED display for seeking field indication. With just 2-3 digital output along with 4-20mA isolated analogue output & inbuilt transmitter power fully, is used only.

Such are paddle type level switches which constantly rotate and are mainly a spring loaded and are rotating vanes on being driven harshly.

Working Principle:
Simply consider the following explicit formulae:
Pressure P(liq) on any surface and container walls at depth h, by the liquid of density d, is: P(liq) = d × g × h + P(air)

where P(air) refers to the air pressure and g denotes the acceleration due to gravity (constant for a given place) at the place of the liquid container. Replacing constants the equation becomes:

P(liq) – P(air) = K × h in short: Liquid levels are showcased through pressure difference. One convenient unit that absorbs pressure with level is mHO (pressure felt at depth in meters while it is put in water) Truman hydrostatic pressure transmitter manages pressure which is output by liquid P(liq) and it is further substracted by air pressure P(air) by making use of a single pressure sensitive diaphragm and air-vent is also provided for, in the connection cable. As Truman hydrostatic pressure transducer is plunged deeper into liquid, the P(liq) becomes higher than P(air) and the diaphragm minutely starts to split.

Such a deformation of the diaphragm does not appear visible pretty clearly, but it is captured by piezo-resistive sensors on the sensitive diaphragm.

Thus, pressure which is released by the liquid is sensed by Truman hydrostatic sensor which directly refers to the depth from the surface of a liquid.
P(liq) – P(air) = K × h

Product Details:

Such are paddle type level switches which constantly rotate and are spring loaded and are rotating vanes which are driven in an unorganized manner or blades which keep rotating but at a slower pace.

Working Principle:
Microwave pulses which are pretty short in form and which are powered by low level of emitted power, are transmitted by the antenna system to the measured product, reflected by the surface of the product and are absorbed back by the antenna system. Likewise, radar waves transmit at the speed of light. The time from taken from emission to its reception of signals remain proportional to the level of in the vessel. Further, there is a special time lengthening procedure, which ensures reliable and precise measurement of the transmission periods which are extremely short in their design.

Unaffected by temperature and pressure:
Microwaves are propagated which remain virtually unaffected by the peaceful temperature and pressure. Hence, such radar sensors become an ideal choice to be put in use under diverse process conditions. There are realised pressures from vacuum up to 160 bar (2320 psi) and temperatures from –40 to upto +400 degree C (that is -40…+752 degree F) and such do not seem to be any problem for radar.

Fluctuations in product organization or even when product changes completely, do not put any influence on the result measurement and such remain independent of product characteristics. As such, any fresh adjustment does not seem to be a necessary step.

Change of Frequency For All Applications:
Premium quality AMPLETECH radar sensors remain accessible in 2 different frequency ranges and such can hence be implemented in a range of applications. K-band instruments are managed in a frequency range of over 20 GHz and such enables the use of smaller antennas and compact process fittings respectively. Further, owing to robust signal focussing, the measuring system secures premium accuracy. C-band instruments are defined by low frequencies around 6 GHz and hence in most of the cases, any dirt build up on antenna systems or foam formation on the products, do not affect the measurement at all.
