032115 We have M-System’s Analog Backup Station Model AB.
Now we have a plan to replace an existing equipment and want to improve our flow control system. We require some additional function on this unit AB.
(1) When switched from MANUAL to AUTO mode, specific fixed value is required to be output.
(2) When start-up after put off the power, fixed preset valued initial output is required.
We considered adding an external circuit in order to get this function. Alternatively, we can consider replacing the AB with any other M-System product, which have this kind function. Please advise.

032131 We are using the synchronous transmitter (SELF-SYNCH) to measure the opening angle of an intake gate in the river and send the output signal of the transmitter to the synchronous receiver in a control room to display the opening angle. As a result of monitor system standardization, we want to convert the output signal (opening angle signal) into a standardized signal of 4 to 20 mA in DC for instrumentation without replacing or modifying the existing synchronous transmitter. Is there any converter suitable for this purpose? The precise operating angle range of the synchronous transmitter is unknown.

032148 We would like to display a 4-20mA DC signal from the two-wire level transmitter. Is there a product to display the water level with alarm output, and the alarm status can be visible?

032152 We like to display a water level in a tank. The 4 to 20mA DC output from a level transmitter is for 0 to 5.00 meter of water level in a oval-shaped tank. Thus, water usage and decreased water level are not proportional. Is there a digital indicator to display water usage?

032162 For the production of pasta, there is a mixing process of raw materials in a tank. The raw materials can be affected by heat. To prevent it, the water temperature surrounding a tank is adjusted by controlling the valves of cold-water and heated-water. This time, we are considering a PLC to control the temperature automatically. The DeviceNet communication bus is ideal to control the valves. Is there any suitable product?
