Meriam is proud to offer an integrated flow measurement system solution using our 40H series Accutube flow elements with the Yokogawa EJA or EJX series of DP and m*riable transmitters.
Yokogawa EJA Series The EJA Series is a best-selling differential pressure transmitter which incorporates Yokogawa’s high accuracy resonating pressure (HARP) silicon sensor, a field-proven technology that is intelligent and offers ultra-high performance. This transmitter’s compact and light weight design has been achieved without compromising performance or service life. The digital principle of the sensor provides repeatability and stability that is superior to analog sensor designs and is virtually immune to the effects of vibration, temperature, static pressure, and overpressure events.
When used with the EJA DP transmitters, Meriam’s 40H / 41H series features direct mount heads with integral 3-valve equalizing manifold that provides ultimate utility. The transmitter bolts directly onto the head eliminating the need to install pressure lines, saving installation and mounting time. They are ideal for plant upgrades, adding measurement points and for new plant installations.
Yokogawa EJX910 The high-performance EJX910 m*riable transmitter features a single-crystal silicon resonant sensor and is suitable to measure liquid, gas or steam mass flow. The EJX910 outputs a 4-20 mA DC signal corresponding to the measured differential pressure, static pressure, process temperature, or dynamically calculated and fully compensated mass flow.
When combining the Accutube and the Yokogawa EJX910 m*riable transmitter, mass flow and corrected volumetric flow measurement applications are handled. The m*riable transmitter provides additional ease of use with features such as:
• Replaces 3 element steam and gas flow systems • One unit does temperature, pressure, DP, and calculates flow from those parameters • Can use one twisted pair to the control room • Configurable with a laptop
