Two-wire flowmeter operates successfully on low supply voltages
October 2001
Flow Measurement & Control
In March 2001, Krohne Altometer introduced the Altoflux 2 W IFM 4042 electromagnetic flowmeter, a unique flowmeter with low power consumption and many other innovative features.
After several fruitless attempts to find the right instrument for their application at their site in Fos sur Mer, Albemarle Corporation turned to Krohne, which recommended its Altoflux 2 W IFM 4042 K. The power supplies at the location (of various brands) all supplied voltages in the range 16 to 18 V, while 24 V is the common standard. So the big question for Albemarle was whether the Altoflux IFM 4042 would function properly at these low-power supply voltages where many other devices had failed before.
The test with the 2-wire instrument concerned a batch application. Two separate containers are filled with sodium sulphite (Na2SO3). The flow is regulated by means of the 4-20 mA output; the pulse output of the electromagnetic flowmeter controls a valve to shut when the desired level is reached in the containers.
The test demonstrated that the Altoflux IFM4042:
* Functions perfectly at low voltages;
* Supplies a stable 4/20 mA current output;
* Provides the client with precise, accurate measuring data.
Cost savings
Due to the satisfactory results of the field test, Albemarle purchased a further IFM 4042 DN 150 for water/glycol measurement. One of the main reasons for its choice was that this electromagnetic flowmeter fits into the requirement for a 2-wire device. Standardisation was the key. Krohne's genuine 2-wire flowmeter was a solution to Albemarle's application needs, as the technicians were already familiar with the 2-wire principle.
At the customer's location, the Altoflux 2 W can be placed on the shelf as a basic Eex device and later, according to the needs of the moment, be installed as an Eex 'd', 'e' or 'i' class device. This significantly reduces the stock level of the product. And lower stocks mean lower costs.
The Altoflux IFM 4042 has been successfully implemented into Albemarle's production process, because of its versatile application possibilities. This customer has finally found what it was looking for - a genuine 2-wire electromagnetic flowmeter functioning flawlessly at the supply voltages present.
