Flow sensor with plain text display

Adjustable level switch Val.Co, a leader in the design and manufacture of pro cess instrumentation, has launched the new Simple R1-M.B77 adjustable level control switch for monitoring liquids in industrial and civil environments. Jan Grobler, Managing Director of GHM Messtechnik South Africa highlighted some of the features: “The Simple R1-M.B77 from Val.Co offers the customer a unique feature in that the rod, which comes in lengths of either one metre or 500 millimetres, can be shortened to the length required to suit the purpose. The level switch is new to the South African market, competitively priced and suitable for various level applications.” The operational principle is based on the drive of a micro-switch, which is located in the head of the instrument, as a result Easy commissioning The FS101 retains the Quick Teach and Delta Flow functions that simplify commissioning – as initially introduced in the FS100 with a bar graph display. Delta Flow ensures the teach-in is not performed until the warm-up phase of the temperature peak is completed and a constant flow is present. This eradicates a frequent source of errors in traditional parameterisation processes. Users also benefit from the device’s trouble free operation via capacitive touchpads. Turck Banner will continue to offer the earlier FS100 devices with a bar graph display. Typical areas of application are the monitoring of cool Flow monitoring is critical in applications that demand reliable and reproducible surveillance of limit values and flow patterns. Flow sensors detect critical deviations of the flow rate in liquid and gaseous media – and being able to monitor the flow visually is just as important as the continuous output signal. Turck Banner recently added the FS101 flow sensor to its line-up. The device will have the same look and feel as all other sensors in the FS+ fluid sensor family and is equally easy to run and commission. The four-digit 12-segment display on the device shows the current flow value clearly as a percentage of the setpoint. The implemented IO-Link smart sensor profile simplifies the conversion of IO-Link flow sensors of other manufacturers to the FS+ devices as process data, parameters and functions are standardised.

The FS+ series of flow sensors now features the same plain text display as the other sensors of Turck Banner’s Fluid+ family. ing circuits in welding applications for example, protection against dry running of pumps, as well as flow monitoring in air ducts and air condition ing equipment. Because of the calorimetric mode used, the media temperature is also monitored. The FS101 flow sensor provides for fast and easy commissioning, high reliability based on error-proof teach-in support with Delta Flow, and easy operation via the plain text display with capacitive touchpads.

of the hydrostatic thrust exerted by the liquid on the float. The absence of moving parts offers maximum ruggedness and reduces the need for maintenance. With an adjustable switching point and closed cell float, the instrument also offers a 3 A Single Pole Double Throw (SPDT) micro-switch as well as a Single Pole Single Throw (STST) option. It has an operating ambient temperature of -30/+55°C with a 90% relative humidity. Easily mounted, threaded or flanged, it has an NBR (oil resistant rubber) flat sealing gasket and of fers a minimum degree of protection of IP65. It is sup plied with a DIN 43650-A plug. “The new adjustable level switch will suit wide rang ing industrial, domestic and agricultural applications where water/liquid level monitoring is crucial. Customers will benefit from its innovative design and it is available in nylon and fibreglass (Model R1-M) or stainless steel/ brass (Model R1) versions,” Grobler said.
