Level Measurement

-

Siemens Milltronics offers a variety of different Level measuring instruments for liquids, solids, slurries and interfaces. Depending on the measuring task, a first distinction can be made between:
 

Point Level Measurement
A binary signal is output when the level falls below or exceeds set limits.

Pointek CLS 100
Compact 2-wire inverse frequency shift capacitance switch for level detection in constricted spaces, interfaces, solids, liquids, slurries and foam.

Pointek CLS 200
A versatile inverse frequency shift capacitance level switch with optional rod/cable choices and configurable output, ideal for detection of liquids, solids, slurries, foam and interfaces; digital version (with PROFIBUS PA) includes a display and provides additional diagnostic features.

Pointek CLS 300
Inverse frequency shift capacitance level switch with optional rod/cable choices and configurable output. It is ideal for detecting liquids, solids, slurries, foam and interfaces in demanding conditions where high pressure and temperatures are present; digital version (with PROFIBUS PA) includes a display and provides additional diagnostic features.

Pointek CLS 500
inverse frequency shift capacitance level switch for detecting interfaces, solids, liquids, toxic and aggressive chemicals in critical conditions of high temperature and pressure; HARTŪ communication for remote commissioning.

Pointek ULS 200
Ultrasonic non-contacting switch with two switch points for level detection of bulk solids, liquids and slurries in a wide variety of industries.

SITRANS LPS200
Rotating switch that detects high, low and demand conditions for bulk solids.

SITRANS LVL100
Compact vibrating level switch for use in liquid applications such as overflow, high, low and demand applications, as well as pump protection. It is ideal for use in confined spaces.

SITRANS LVL200
Vibrating level switch for use in all liquid and slurry applications such as overflow, high, low, and demand applications, as well as pump protection. For use in SIL-2 applications.

SITRANS LVS100
The SITRANS LVS100 is a vibrating point level switch for bulk solids.

SITRANS LVS200
Vibrating point level switch with unique robust tine design, for use on bulk solids.


Continuous Measurement
Dynamic processes are constantly monitored and transmitted as an analog signal or a digital value. Various technologies are available: ultrasonic, radar, capacitance and hydrostatic methods

Our product range comprises the following methods:

Radar
Non-contact level measurement of liquids and solids, even under extreme conditions such as high pressure and temperatures, atmospheres with steam or gases and vacuums.

Guided Wave Radar
SITRANS LG200 is a guided wave radar transmitter for short and medium range level, level/interface and volume measurement of liquids and solids. It is unaffected by changes in process conditions, high temperatures and pressures, and steam.

Ultrasonic
Non-contact level measurement of liquids and solids, even under harsh ambient conditions such as vibrations, dust formation etc.

Capacitance
Product contacting level measurement of liquids, solids, interfaces and foam, even at extreme pressures and temperatures.

Hydrostatic
Level measurement of liquids in open and closed containers and reactors, even under difficult conditions, such as the formation of foam.

The SITRANS P pressure/differential pressure transmitters allow the level to be determined directly or via pressure sensors. For level measurment in open containers the gage pressure transmitters P300 or DSIII are available. For metering in closed containers, differential pressure transmitters DS III series can be used.

A value for money alternative for non-aggressive liquids e.g. water/liquid waste is the SITRANS P MPS cylinder probe.

Open Channel Flow
Open Channel Flowmeters use a non-contacting level measurement reading and mathematical algorithms to provide continuous flow monitoring of flumes, weirs or channels.

SITRANS Probe LU
The SITRANS Probe LU is a 2-wire, loop powered ultrasonic transmitter for level/volume/flow monitoring of liquids in storage vessels, simple process vessels, and open channels.

MultiRanger 100/200
The MultiRanger is a versatile short- to medium-range ultrasonic single- and multi-vessel level monitor / controller for virtually any application in a wide variety of industries.

HydroRanger 200
The HydroRanger 200 is an ultrasonic level controller for up to six pumps - control, differential control, and open channel flow monitoring.

HydroRanger Plus
The HydroRanger Plus is an ultrasonic level controller for control of wet wells and reservoir pump operations, differential control, and open channel flow monitoring, with energy saving algorithms.

EnviroRanger ERS 500
The EnviroRanger is a complete ultrasonic level controller for monitoring and control of water distribution and wastewater collection systems, with energy saving algorithms.

OCM III
The OCM III is a high accuracy ultrasonic flow monitor for open channels
