ES Series: Electronic Transmitter for Variable Area Flow Meters
The ES Series Electronic Transmitter is an advanced solution designed to enhance the functionality of variable area flow meters by providing precise electronic signal transmission. Specifically engineered for integration with Heinrichs’ range of variable area flow meters, the ES Series ensures accurate and reliable data transfer for process monitoring and control. This transmitter converts the mechanical flow measurement into a standard electronic signal, making it ideal for applications that require remote monitoring, data logging, or integration into automated control systems.
Functionality
The ES Series transmitter operates by converting the position of the float within the variable area flow meter into an electronic signal. This process involves a high-precision sensor that detects the float’s position as it moves in response to fluid flow. The transmitter then processes this information and outputs it as a 4-20 mA or other standard signal, compatible with most industrial control systems.
This electronic output allows for real-time monitoring of flow rates and provides the ability to integrate flow data into a broader process control system. Whether used in conjunction with local displays or remote monitoring systems, the ES Series ensures that accurate flow data is consistently available, enhancing both operational efficiency and process safety.
