Product catalog summary
General Overview: Electromagnetic Asameters® are versatile flow meters designed for conductive liquids, suitable for a wide range of applications including chemical, potable water, food, petrochemical, pharmaceutical, and wastewater treatment. They can handle both small (DN4) and large (DN1000) flow rates and are unaffected by liquid density and viscosity. Installation can be horizontal or vertical, with options for integrated or remote electronics, supporting cable lengths up to 200 meters.
Technical Specifications: The flow meters have a measuring range of 0.3-12 m/s, with an accuracy of ±0.5% and repeatability of ±0.1%. They can withstand a maximum pressure of 10 bar, with connections available in WAFER, DIN 11851, SMS, and TRICLAMP, all made from AISI 316L stainless steel. The measuring tube is constructed from AISI 304 stainless steel.
Output and Input Signals: The devices offer a 0/4-20 mA output with a maximum load of 1,400 Ω, a programmable pulse output (up to 10 KHz), and open collector outputs for alarms. They include two relays for system error monitoring and dosing, with input signals for total reset, lock, autozero, and dosing control.
Construction Materials: Internal linings are available in PTFE, Hard Rubber, and DIFLEX. Electrodes are typically AISI 316L, with options for Titanium, Hastelloy “C”, and Tantalum. The measuring tube is AISI 304 coated, and the board cover is die-cast aluminum epoxy painted RAL 7001.
Environmental and Mechanical Features: Operating temperatures range from -10° to +75°C, with mechanical protection rated at IP65 or optionally IP67/68. The maximum fluid temperature depends on the coating material, reaching up to 160°C for DIFLEX.
Additional Features: The meters feature a backlit LCD graphic display and an optical keyboard with dynamic menus. They support bidirectional flow and have programmable damping from 0.1 to 100 seconds. Auto-diagnostic features are included for error detection.
Dimensional Specifications: Detailed dimensional drawings are provided for various types (AW, AD-AS, AT) and sizes (DN15 to DN125), with dimensions in millimeters. Standard lengths (L1 and L2) and pressure ratings (PN) are specified for each size.
Temperature Specifications: The maximum fluid temperature is 40°C (104°F) for environmental conditions. Electronic components operate between -10°C and +75°C, while the measuring tube can handle temperatures from -30°C to +160°C, depending on the coating material.
Additional Features: The meters are available in intrinsically safe and explosion-proof versions, compliant with ATEX Directive 94/9/CE. Communication options include RS 232 and RS 485 serial interfaces.
