Specialist Instrumentation for Specialised Applications
Over 30 years of experience in the design and development of high-quality instrumentation for process industries puts Val.co, part of the GHM Group, at the forefront to supply specialist liquid level, flow, pressure and temperature instrumentation to industrial sectors from agriculture to water treatment.
Val.co’s ability to design instrumentation and supply prototypes at relatively short notice in order to meet specific customer requirements, is a flexibility that is an integral part of the Val.co Centre of Competence operations.
“Val.co is renowned for its focus on customer satisfaction and the supply of highly accurate, precision and reliable instrumentation” said Jan Grobler, Managing Director of GHM Messtechnik in South Africa. “We have already supplied level transmitters to the South African mining industry for mining oil level applications. I believe that many other process industries such as HVAC, petrochem, oil and gas can also benefit, not only from the performance of the Val.co instrumentation, but also from its cost effectiveness”
said Grobler.
The company’s Centre of Core Competence based in Milan, was established to develop and design precise and robust instrumentation that will operate under the most demanding of conditions and they carry approved construction certification for explosive-proof ATEX Exd-Exi a, EAC and RINA for naval applications.
The Centre of Competence is geared towards using the latest technology to extend the expertise of temperature sensors and electronics, thereby expanding the specialised instrumentation offering of industrial sensors across all applications.
Level Sensors and Switches
The Val.co range of continuous level sensors and level switches offer float, conductive, capacitive, optical control and measurement technology in single and multiple unit formations with up to six independent
contacts. Level sensors with current or voltage output can be programmed for customised executions that the customer specifies.
“The range of level sensors can be applied across all industries where level measurement is a critical function. In continuous operation they are temperature resistance up to +1050C. It is a quality range and competitively priced” Grobler added.
The level sensors supply accurate monitoring controls of water, oils, gas oils, gasolines, solvents, milk, beverages, solids, powders and granules. The Val.co range includes: small float switches, Linear-LC, limit level switch for side installation, multipoint and simple of double contact limit level switches.
The proven reed designed meters are constructed from brass and stainless steel and plastic (Polypropylene, PVC, PVDF) and can be vertically or horizontally mounted.
For vertical installation the level control, with the dimension and number of contacts required, is mounted vertically in the tank and secured by means of the process connection, threaded or flanged. The change in liquid level moves the float which actuates the reed contact, housed and sealed inside the guide rod, activating the signal corresponding to the set level.
In the case of horizontal mounting, the level control is installed on the wall of the tank at the height of the level to be monitored. In this way more levels are able to be monitored by the installation of the proper number of level switches. The level control can operate as a device with contact NC or NO, as a function of the position.
Flow and Pressure Sensors and Switches
Val.co’s flow switches use piston or paddle control technology with magnetic contact whilst visual indicators and signal processors control and measure particles with piston, membrane, bourdon tube and piezoresistive technologies.
All instrumentation devices are compliant with quality systems and are SGS UNI EN ISO 9001 certified. They carry the CE product certification and CESI certification for explosion proof performance.
Grobler concluded, “Val.co instrumentation gives the South African process sectors the latest in measuring and monitoring technologies enabling these industries to embrace smart factory and Industry 4.0 and 4.1 advances. If it is a specialised application that requires a high level of accuracy and precision, then we have the specialist instrumentation to perform these functions”.
