The SF series visual flow transmitter integrates tangent thread technology and isolation sealing circuit, which can provide accurate flow measurement and control in harsh environments. The two-wire live circuit design provides a 4-20mA output proportional to the flow rate. The transmitter can measure flow in two directions and can be installed in any position. The SF11 model has a transparent polycarbonate visual flow indicator. It also comes with LED power indicator, adjustable zero point, reverse phase, and overcurrent protection.
