1. Planning information 1. Planning information 1.1 Areas of application The flow measurement device Flowmax 44i is designed to measure dynamic flow in pipes and tubes. This flowmeter is suitable for liquids only. The Flowmax 44i is used in Chemicals supply for controlling, logistics, monitoring ...
2.1 Installation instructions NOTICE! The housing of Flowmax 44i is labeled with an arrow symbolizing the direction of the flow measurement. The flow meter has to be installed in a way so that the flow-through is in the same direction as the arrow symbol.
2. Assembly and installation Particles present in the flow stream may result in measuring errors. When using pumps, Flowmax 44i must be installed in flow direction on the pressure side, on order to ensure sufficient pressure. Do not exceed the maximum pressure allowance for of the Flowmax 44i (see section 5.2 Technical specifications).
If it is not possible to mount the flowmeter vertically, then mount the instrument in a location where the pipe will be filled at all times. The best measuring result is achieved if bubbles do not pass through Flowmax 44i. Fig. 4: Mounting possibilities For applications with a “clean design“...
Flowmax 44i warps and the process connection breaks off. To ensure the mechanical stress-free mounting of Flowmax 44i, is on site to ensure by appropriate measures that no forces can act on the plastic housing, for example, a flexible metal hose or a strain curve.
Always shut off or disconnect electrical power at service panel and WARNING! lock switch or breaker and tag to prevent energizing electrical power during work or while Flowmax 44i is not assembled and installed. Wiring installation, disassembly and removal must be performed by qualified persons experienced and knowledgeable about electrical work.

3. Commissioning 3. Commissioning NOTE: If Flowmax 44i is used for a fluid other than water the "basic trim" has to be carried out during commissioning. Therefore the device has absolutely be filled with medium. The basic trim can be done on the device display (alternatively FlowCon).
The default password for Flowmax 44i is 41414. The user level will remain active for 30 minutes after the last press on any button. 200 seconds after the last key press, the device skips the menu and returns to the display mode, which does not apply to the menu items diagnostic and dosing.
Spanish, French and German. 3.2.2 Dosing The Flowmax 44i can be configured for manually dosing by choosing the dosing function via the user display. The Volume “Dosing Quantity“ and the “Dosing Time“ are freely adjustable. The dosing time is intended as a safeguard against unintentional overspill.
Flowmax 3. Commissioning Creeping suppression The creeping suppression excludes flow measurements that result from convection in a narrow band around zero, even with a closed valve. At the factory, the creeping suppression is set at a standard value in relation to the cross-section of the flowmeter.
Basic Trim The “Basic Trim” function insures that the flowmeter is conforming to the media NOTICE! specific characteristics. To execute this function, Flowmax 44i runs a self- diagnostic function which optimizes all important parameters. This process lasts approximately 1 minute.
Flowmax 3. Commissioning 3.2.4 General Adjustment Reset Counter The volume counter of Flowmax 44i can be reset. Example of operation see appendix. Important! Once reset, counter values cannot be restored. After a reset the counter works IMPORTANT! normally. Hysteresis The limit values can be provided with a hysteresis.

The pulse value determines the flow volumes for which an output pulse will be emitted. Choose a configuration which will neither exceed the maximum output frequency of the Flowmax 44i (10kHz) nor the maximum input frequency of the control. If the maximum frequency is exceeded the Flowmax 44i will not output pulses correctly.

Flowmax 3. Commissioning Temperature measurement for the analog output Via the analog output the measured temperature is output. The temperature sensor is not wetted. It is used to calculate the extent of the measuring channel. The sensor is influenced by the ambient temperature. The temperature value will become sluggish, because it measures the plastic - Temperature inside the sensor pocket.
Flowmax 3. Commissioning 3.2.7 Digital Outputs Q1 and Q2 (Q2 only available with 8-pin plug) The digital outputs Q1 and Q2 can be used as a pulse output, for signaling the empty pipe message for controlling a dosing valve or to limit monitoring. All outputs become high resistant if voltage falls below 16V.
