Batch Controller Model 515

Α batch controller that covers most fluid batching requirements that use one or two stage control valves. Starting , stopping or setting the preset quantity for each batch can be achieved from the front keypad or further automated via serial communications. The hardware I/O caters for signals such as End Of Batch, Flow Alarm and Pulse Output. The state of the relays can be defaulted to either "open" or "closed".

The 515 Batch Controller is a dual stage batch controller for reliable measurement of preset quantities. Used as a single or dual stage controller it is suitable for fast batch applications. It provides the operator with clear local readout and can be controlled via communications in more automated systems. There is quick access to commonly used preset values directly from the front panel if access has been authorized.
Automatic overrun compensation caters for system delays such as valve closure for precise volumes. The instrument is compatible with a wide range of flowmeter signal outputs, including analogue 4 -20mA, millivolt signals, reed switches, Namur proximity switches and pulse trains via its smart front-panel program selection. Different versions are available for pulse/frequency or analogue outputs.

Variable Area Flow Meter

Description
The Variable Area Flow meter is an instrument for measuring the flow of liquids or gases in pipelines. It includes a vertical tube through which the fluid flows whose diameter increases from the bottom to the top and a float which can move vertically in the tube. As the flow increases this float moves to a higher position until its resistance to the fluid flow is balanced by the float’s buoyed weight in the fluid, a value which is constant and independent of the flow rate. The position of the float is a measure of the flow rate. The flow rate values can be read on a scale.

Features
Mechanical display or LCD display;
Robust and universal;
The short-stroke design allows the measurement of high flowrate using a relative short metering tube;
Special application is for hazardous, dangerous or aggressive fluid, for high temperature and high pressure rates;
All stainless steel design provides a safe measurement of a variety of liquids, gases and steam-
The measuring section can be equipped with a heating jacket ;
Standard rotameter is mounted in a vertical pipeline with flow direction upwards.

Operating Principle:
Turbine Flow Meters use the mechanical energy of the liquid to rotate a rotor in the flow stream. Fluid entering the meter first passes through an inlet flow straightener that reduces its turbulent flow pattern. As each turbine blade passes through the magnetic field generated by the meter's magnetic pickup, an AC voltage pulse is generated. These pulses provide an output frequency that is proportional to volumetric flow. The generated signal is converted into engineering units (liters, cubic meters, gallons etc.) on the local display where applicable. Optional accessory modules can be used to export the signal to other equipment.
