MJK Automation

What MJK Automation does

MJK Automation is a manufacturer of hydrostatic level measurement and water-quality instrumentation serving industrial, municipal, and environmental water-monitoring customers. The company is positioned as a level-measurement specialist brand within the Xylem Analytics portfolio and operates legally through Xylem Analytics Germany Sales GmbH & Co. KG, with trademarks ultimately held by Xylem Inc. (NYSE: XYL). Founded in 1977 and headquartered in Nærum, Denmark, MJK has historically focused on hydrostatic level transmitters and now fields an eight-product portfolio spanning the MJK Expert series (Models 1400, 3400, 7060, and 7070/7070D) for continuous level measurement, the MJK 7030 float-based level switch for point-level detection, the MJK 780 automated water sampler, and the MJK pHix Compact pH/redox meter. Customer segmentation is application-driven: primary verticals are municipal water management and wastewater treatment, with secondary use cases in industrial processes, aquaculture, oceans and coastlines, and groundwater monitoring. The business model is B2B industrial-instrumentation hardware sales, typically on a quote-based pricing model, executed through Xylem Analytics' direct enterprise sales channel (xylemanalytics.com), an e-commerce storefront for accessories and consumables (shop.ebro.com), and the broader Xylem global distribution network. Marketing is conducted at the Xylem Analytics portfolio level through content marketing, newsletters, video, webinars, and trade shows, with MJK's product page ecosystem tied into shared customer support, documentation, and service infrastructure.

Expansion highlights4 records

Broad incumbents

• Emerson (Rosemount): Diversified industrial automation conglomerate whose Rosemount line includes level, pressure, and flow instrumentation widely deployed in water/wastewater and process plants. A broader incumbent than MJK, but competes head-to-head in municipal and industrial water level applications.
• ABB Measurement & Analytics: Global automation incumbent with a level measurement product line targeting water, wastewater, and process industries. Competes with MJK in industrial and municipal water applications via broader automation bundles.
• YSI (a Xylem brand): Sister brand within Xylem Analytics focused on water quality sensors (DO, conductivity, turbidity). While not a direct level-measurement competitor, YSI shares MJK's distribution, customer base, and parent company, and is frequently bundled with MJK products in integrated water monitoring solutions.
• Yokogawa Electric: Japanese industrial automation and instrumentation company with a level and flow measurement portfolio serving water utilities and industrial process customers. Overlaps with MJK in municipal water and wastewater monitoring.
• Siemens (Process Instrumentation): Global industrial automation leader offering level, flow, and pressure measurement under its Process Instrumentation portfolio. Overlaps with MJK's hydrostatic level transmitter use cases in municipal water and wastewater treatment plants.

Direct peers

• Hach (Danaher): Specialist in water quality analysis and monitoring instrumentation serving drinking water and wastewater customers. Directly comparable to MJK's pHix Compact and broader water monitoring portfolio, with overlapping municipal and industrial water customers.
• VEGA Grieshaber: German-based specialist in level, switching, and pressure measurement instrumentation for water, wastewater, and industrial process markets. Like MJK, VEGA is a privately held, level-measurement-focused company competing in the same municipal and industrial water/wastewater use cases.
• Endress+Hauser: Global industrial measurement instrumentation supplier with a deep level, flow, and analytical portfolio serving water, wastewater, and process industries. Directly comparable to MJK's hydrostatic level transmitters and broader Xylem Analytics offerings, especially in municipal water.
• KROHNE Group: Family-owned industrial process instrumentation specialist with strong focus on flow and level measurement for water, wastewater, and chemical applications. Highly comparable niche profile to MJK's level-measurement specialization.
• Flowline: U.S.-based specialist in liquid level, flow, and leak detection instrumentation for water, wastewater, and chemical applications. A comparable niche player competing with MJK in hydrostatic and float-based level measurement for industrial and municipal customers.
